More about time

General information. Physical properties of time

Time can be viewed in two ways: as a mathematical system created to help our understanding of the universe and the course of events, or as a dimension, part of the structure of the universe. In classical mechanics, time does not depend on other variables and the course of time is constant. Einstein's theory of relativity, on the contrary, states that events that are simultaneous in one frame of reference can occur asynchronously in another if it is in motion relative to the first. This phenomenon is called relativistic time dilation. The above time difference is significant at speeds close to the speed of light, and has been experimentally proven, for example, in the Hafele-Keating experiment. The scientists synchronized five atomic clocks and left one motionless in the lab. The rest of the clock flew around the Earth twice in passenger planes. Hafele and Keating found that "traveling clocks" lag behind stationary clocks, as predicted by relativity theory. The impact of gravity, as well as the increase in speed, slows down time.

Time measurement

Clocks define the current time in units of less than one day, while calendars are abstract systems that represent longer time spans such as days, weeks, months, and years. The smallest unit of time is the second, one of the seven SI units. The standard of a second is: "9192631770 periods of radiation corresponding to the transition between two hyperfine levels of the ground state of the cesium-133 atom."

Mechanical watches

Mechanical clocks usually measure the number of cycles of events of a given length, such as a pendulum swinging once per second. A sundial tracks the movement of the Sun across the sky throughout the day and displays the time on the dial using a shadow. Water clocks, widely used in antiquity and the Middle Ages, measure time by pouring water between several vessels, while hourglasses use sand and similar materials.

The Long Now Foundation in San Francisco is developing a 10,000-year-old clock called the Clock of the Long Now, which should last and remain accurate for ten thousand years. The project is aimed at creating a simple, understandable and easy-to-use and repair structure. Precious metals will not be used in the design of the watch. Currently, the design involves human service, including winding the watch. Time is kept by a dual system consisting of an inaccurate but reliable mechanical pendulum and an unreliable (weather-related) but accurate lens that collects sunlight. At the time of this writing (January 2013), a prototype of this watch is being built.

atomic clock

At present, atomic clocks are the most accurate instruments for measuring time. They are used to ensure accuracy in broadcasting, global navigation satellite systems, and worldwide timekeeping. In such clocks, the thermal vibrations of atoms are slowed down by irradiating them with laser light of the appropriate frequency to a temperature close to absolute zero. Time calculation is carried out by measuring the frequency of radiation resulting from the transition of electrons between levels, and the frequency of these oscillations depends on the electrostatic forces between the electrons and the nucleus, as well as on the mass of the nucleus. Currently, the most common atomic clocks use cesium, rubidium, or hydrogen atoms. Cesium-based atomic clocks are the most accurate in long-term use. Their error is less than one second per million years. Hydrogen atomic clocks are about ten times more accurate for shorter periods of time, up to a week.

Other time measuring instruments

Other measuring instruments include chronometers, which measure time with an accuracy sufficient for use in navigation. With their help, determine the geographical position, based on the position of stars and planets. Today, a chronometer is commonly carried on ships as a backup navigational device, and marine professionals know how to use it in navigation. However, global navigation satellite systems are used more often than chronometers and sextants.

UTC

Around the world, Coordinated Universal Time (UTC) is used as the universal time measurement system. It is based on the International Atomic Time (TAI) system, which uses the weighted average of over 200 atomic clocks around the world to calculate accurate time. Since 2012, TAI has been 35 seconds ahead of UTC because UTC, unlike TAI, uses a mean solar day. Since the solar day is slightly longer than 24 hours, coordinate seconds are added to UTC to coordinate UTC with the solar day. Sometimes these seconds of coordination cause various problems, especially in areas where computers are used. To avoid these problems, some institutions, such as Google's server department, use leap seconds instead of leap seconds, lengthening a series of seconds by milliseconds so that these lengthenings add up to one second.

UTC is based on atomic clocks, while Greenwich Mean Time (GMT) is based on the length of a solar day. GMT is less accurate because it depends on the Earth's rotation period, which is not constant. GMT was widely used in the past, but now UTC is used instead.

Calendars

Calendars are made up of one or more levels of cycles, such as days, weeks, months, and years. They are divided into lunar, solar, lunisolar.

Lunar calendars

Lunar calendars are based on the phases of the moon. Each month is one lunar cycle, and a year is 12 months or 354.37 days. The lunar year is shorter than the solar year, and as a result, lunar calendars only synchronize with the solar year once every 33 lunar years. One of these calendars is Islamic. It is used for religious purposes and as the official calendar in Saudi Arabia.

solar calendars

Solar calendars are based on the movement of the Sun and the seasons. Their frame of reference is the solar or tropical year, which is the time it takes for the Sun to complete one cycle of the seasons, such as from winter solstice to winter solstice. A tropical year is 365.242 days. Due to the precession of the Earth's axis, that is, the slow change in the position of the Earth's axis of rotation, the tropical year is about 20 minutes shorter than the time it takes for the Earth to complete one orbit around the Sun relative to the fixed stars (sidereal year). The tropical year gradually gets shorter by 0.53 seconds every 100 tropical years, so reform is likely to be needed in the future to keep solar calendars in sync with the tropical year.

The most famous and widely used solar calendar is the Gregorian. It is based on the Julian calendar, which in turn is based on the old Roman one. The Julian calendar assumes that the year consists of 365.25 days. In fact, the tropical year is 11 minutes shorter. As a result of this inaccuracy, by 1582 the Julian calendar was 10 days ahead of the tropical year. The Gregorian calendar came into use to correct this discrepancy, and gradually replaced other calendars in many countries. Some places, including the Orthodox Church, still use the Julian calendar. By 2013, the difference between the Julian and Gregorian calendars is 13 days.

To synchronize the 365-day Gregorian year with the 365.2425-day tropical year, a 366-day leap year is added to the Gregorian calendar. This is done every four years, except for years that are divisible by 100 but not divisible by 400. For example, 2000 was a leap year but 1900 was not.

lunisolar calendars

Lunisolar calendars are a combination of the lunar and solar calendars. Usually the month in them is equal to the lunar phase, and the months alternate between 29 and 30 days, since the approximate average length of the lunar month is 29.53 days. To keep the lunisolar calendar in sync with the tropical year, every few years a thirteenth month is added to the lunar year. For example, in the Hebrew calendar, the thirteenth month is added seven times over the course of nineteen years - this is called the 19-year cycle, or the Metonic cycle. The Chinese and Hindu calendars are also examples of lunisolar calendars.

Other calendars

Other types of calendars are based on astronomical phenomena such as the movement of Venus or historical events such as a change of rulers. For example, the Japanese calendar (年号 nengō, literally, era name) is used in addition to the Gregorian calendar. The name of the year corresponds to the name of the period, which is also called the emperor's motto, and the reign year of the emperor of that period. Upon accession to the throne, the new emperor approves his motto, and the countdown of the new period begins. The emperor's motto later becomes his posthumous name. According to this scheme, the year 2013 is called Heisei 25, that is, the 25th year of the reign of Emperor Akihito of the Heisei period.

Do you find it difficult to translate units of measurement from one language to another? Colleagues are ready to help you. Post a question to TCTerms and within a few minutes you will receive an answer.

We are used to the fact that in one kilogram there are a thousand grams, and in one kilometer there are a thousand meters. And everyone understands that 1.5 kilometers is 1500 meters, and 1.3 kilograms is 1300 grams. When it comes to hours and minutes, the usual picture collapses, because 1.2 hours is not at all 1200 minutes, and not 120 minutes, and not 1 hour and 20 minutes. And sometimes it is very necessary to convert minutes to hours, or hours to seconds. Very often, for example, such a need arises when solving problems in physics, when it is necessary to express the speed, expressed in kilometers per hour, in meters per second. There is nothing complicated here.

How to convert minutes to hours

How many minutes are in 1 hour? 60. Actually, proceeding from this, it is already possible to solve the task.

To convert hours to minutes, just multiply the number of hours by 60:

1 hour = 1 * 60 minutes = 60 minutes

3 hours = 3 * 60 minutes = 180 minutes

5.3 hours = 5.3 * 60 minutes = 318 minutes, or = 5 hours + 0.3 hours = 5 hours + 0.3 * 60 minutes = 5 hours 18 minutes

2.14 hours = 2.14 * 60 minutes = 128.4 minutes

The last example shows that this operation works not only for integer values, but also for fractional ones.

If to convert hours to minutes it was necessary to multiply by 60, then to convert minutes to hours, you need to divide the number of minutes by 60:

120 minutes = 120 / 60 = 2 hours

45 minutes = 45 / 60 = 0.75 hours

204 minutes = 204 / 60 = 3.4 hours, or = 3 hours 24 minutes

24.6 minutes = 24.6 / 60 = 0.41 hours

If you need to convert a formula that contains other units of measurement, simply replace one value with another, following the rules above. The unit of measure "hour" should be changed to "60 minutes" and "minute" should be changed to "1/60 hour".

If you get a fraction when converting hours to minutes, you can continue the translation and find out how many seconds are the fractional part of a minute.

How to convert minutes to seconds

Since there are sixty seconds in one minute, it is also not difficult to convert one value to another. To convert minutes to seconds, you need to multiply the time expressed in minutes by 60:

1 minute = 1 * 60 seconds = 60 seconds

3 minutes = 3 * 60 seconds = 180 seconds

5.3 minutes = 5.3 * 60 seconds = 318 seconds, or = 5 minutes + 0.3 minutes = 5 minutes + 0.3 * 60 seconds = 5 minutes 18 seconds

This operation is applicable to both integer and fractional values.

To convert seconds to minutes, divide the number of seconds by 60:

120 seconds = 120 / 60 = 2 minutes

45 seconds = 45 / 60 = 0.75 minutes

204 seconds = 204 / 60 = 3.4 minutes, or = 3 minutes 24 seconds

24.6 seconds = 24.6 / 60 = 0.41 minutes

When converting various formulas, the unit of measurement "minutes" must be replaced by "60 seconds", and "second" by "1/60 of a minute".

Now, knowing how to convert seconds to minutes, and minutes to hours, you can easily and simply

convert seconds to hours

Since there are 60 seconds in 1 minute and 60 minutes in one hour, it turns out that in one hour 60 * 60 = 3600 seconds. And this means that to convert seconds to hours, you need to divide them by 3600:

8640 seconds = 8640 / 3600 = 2.4 hours

Conversely, to convert hours to seconds, multiply by 3600:

1.2 hours = 1.2 * 3600 seconds = 4320 seconds

You can continue the transformation further. There are 24 hours in a day, 7 days in a week, and as many as 365 days in a year (366 in a leap year). Focusing on the above examples, I think you can easily convert one unit of time to another.

Many events are presented in minutes. But often, for ease of perception or some further calculations, it is required to represent these minutes in hours. How to do it? Read the instructions.

As you can see, converting minutes to hours is quite simple. You just need to remember the rules of multiplication, division and subtraction.

Do you find it difficult to translate units of measurement from one language to another? Colleagues are ready to help you. Post a question to TCTerms and within a few minutes you will receive an answer.

Let's take a look at how to convert minutes to hours and vice versa. To begin with, we agree that we will definitely need knowledge of arithmetic. After all, one cannot do without calculations here. If you can’t do them in your mind or on a piece of paper, then use a calculator. Below will be presented almost all the options for how to convert minutes to hours.

From ancient times to modern times

Look at the dial. It has 60 divisions, that is, 60 seconds (minutes). Those who are friends with mathematics have long noticed that this science is similar to trick, mysticism, and thus amuses. Ancient people were no more stupid than our contemporaries, on the contrary, they even succeeded in something.

What we have today:

Of course, 3600 seconds was obtained by multiplying 60 minutes * 60 seconds. Let's take another look at the dial: for example, the hour (short hand) is at 12, and the minute (long) shows that it is 20 minutes. That is twenty minutes past one. Now let's see how to convert minutes to hours with this example.

Simple and complex calculations up to 1 hour

Remember arithmetic in elementary school and 5th grade: there were fractions. What are we getting at? 1 hour = 60 min. And we only have 20 minutes. It may be incorrect to note that only 20/60 hours have passed. But we know that fractions can be reduced. Let's do that:

In total, 1/3 hour has passed, or, if we divide, then 0.33.

Consider another option: what does a quarter of an hour mean? How to convert minutes to hours vice versa?

1/4 hour = 15 minutes. How did it happen?

15 min./60 min. = 1/4.

How to correctly write 10 minutes in hours? The solution technique is identical:

10 min./60 min. = 1/6 hour = 0.167 hours. It is clear that such a record is incorrect, so it is recommended not to translate for 10 minutes.

Over an hour

Many of us have seen how, for example, it is written in the annotation for the film its duration: 150 minutes. How to convert minutes to hours in this case? Please note that there will be no more fractions. Why? Because in the previous section we were talking about a time that lasted less than 1 hour. And now it's the other way around. On the one hand, everything will look easy, but in fact it is more difficult.

So, back to 150 minutes. In order not to think for a long time, let's mentally sum up 60 minutes until we get to the cherished 150: 60 minutes. + 60 min. = 120. We must stop, because if we add another 60 minutes, it will be 180, and we have a movie only 150 minutes long. Back to our 120 minutes. Of course, it's 2 hours. And now subtract 120 from 150 minutes. It will turn out 30.

You can do it differently. Stop at 120 minutes and mentally catch up with the missing half hour. Here is the result: 150 min. = 2 hours 30 minutes = 2.5 hours.

And how to get from 1.5 hours minutes? Immediately imagine 1 hour 30 minutes: 60 + 30 = 90 minutes.

Another option: an arithmetic fraction is one whole and five tenths, which after conversion looks like: 15/10 = 3/2. In fact, 1.5 hours is 3/2 hours.

Imagine a lesson in 3rd grade that deals with fractions. There were also color pictures that clearly showed what 5/6 or 1/2 means.

Why are such complexities required?

Imagine that you are studying the train schedule. As a rule, they write, for example, travel time: 1 hour 5 minutes. Everything seems to be clear. But let's imagine how many minutes it is? 65 minutes. Other: 2 hours 35 minutes? Let's calculate:

2 hours = 120 minutes, add another 35 minutes. As a result: 120 + 35 = 155 min.

So we looked at how to convert minutes to hours and vice versa. In order to be able to calculate quickly, it is desirable to know the basics of mathematics. If you can’t mentally calculate, you should solve the problem on a piece of paper.
