It's very simple: 1 degree is divided into 60 shares, which are called "moments". And every minute, in turn, contains 60 "seconds". As you can see, there is a complete analogy with those minutes and seconds, which for us has always been more associated with the time dimension than the angles and coordinates. So comfortable uniformity of dimension, we owe to the inhabitants of Babylon, from which the legacy of modern civilization got all these hours, minutes and seconds. The Babylonians used a sexagesimal system of calculation.

Of course, apart from minutes and seconds are smaller fractions of a degree. Unfortunately, the simplicity of the ancient ends and the modern bureaucracy. It would be logical to divide by 60 a share, or at least on the usual milliseconds, microseconds, etc. But in the SI system, and home Standards this is not recommended, so fractions of a degree, smaller angular seconds should be recalculated in radians. Fortunately, the measurement of such small angles may need only enough of the prepared. We can meet more of the simple tasks.

So, to the measure of the angle specified in format (degrees minutes seconds convert to decimal degrees, should be to the whole number of degrees to add the number of minutes divided by 60 and the number of seconds divided by 3600. For example, the geographic coordinates of a wonderful place in the city of Krasnodar is 45° 2' 32" North latitude and 38° 58' 50" East longitude. If you count it in the usual degree, we obtain 45° + 2/60 + 32/3600 = 45.0421° North latitude and 38 + 58/60 + 50/3600 = 38.9806 East longitude.

To convert seconds to hours, it is enough to divide number of seconds by 3600 (since one hour has 60 minutes and each minute 60 seconds. For this you can use an ordinary calculator. Even enough that there is almost any cell phone.

However, it should be noted that the number of hours is sure to be a fractional (decimal: x.y hours). Although decimal representation of time (especially time intervals) and more convenient when carrying out intermediate calculations, the final answer, such a representation is used relatively rarely.

Depending on the specific tasks may need to specify time in the form of: x hours y seconds. In this case, it is sufficient to divide evenly the number of seconds by 3600 - the whole part of the division is the number of hours (x) and modulo the number of seconds (y).

If in the end it should be a specific point in time (clock reading), then the solution is likely to present in the form of: x hours, y minutes, z seconds. For this number of seconds will first have to divide evenly into 3600. The resulting quotient will be the number of hours (Kh). The remainder of the division is necessary again to divide evenly into 60. Obtained in this step, the quotient will be the number of minutes (y), and the remainder of dividing the number of seconds (z).

In order to solve the inverse problem, i.e. to convert seconds to hours, all of the above steps needs to be done in reverse order. Accordingly, for the first case, the number of seconds be x.y*3600, for the second - x*3600+y, and for the third - x*3600+y*60+z.

Although the use of the above-described method and should not cause problems with unit calculations, when large volumes of computation (e.g., processing of experimental data), this process can take time and cause errors. In this case it is better to use the appropriate programs.

For example, using MS Excel, once you enter the necessary formulas to obtain ready-made results. The preparation of suitable formulas do not require user programming skills and is available even to schoolchildren. For example, let's make a formula for our case.

Let the initial number of seconds entered in cell A1.

Then, in the first embodiment, the number of hours will be: =A1/3600

In a second embodiment, the number of hours and seconds: =INTEGER(A1/3600) =MOD(A1;3600), respectively.

In the third embodiment, the number of hours, minutes and seconds can be calculate by the following formulas:

=INTEGER(A1/3600)

=INTEGER(MOD(A1;3600)/60)

=MOD(MOD(A1;3600);60)

# Advice 3: How to convert seconds to degrees

Measure in degreesAh, minutes and seconds is most commonly used to denote geographical or astronomical coordinates. As in the time dimension, each arc minute contains 60 seconds, and the degree of fit 60 minutes. This sexagesimal system of calculation is saved from the time of ancient Babylon. But in modern systems of standardization, including those used in Russia, the SI uses the decimal calculus, so quite often you want to translate minutes and seconds to decimal degrees.

Instruction

1

Share known you the number of seconds by 3600 to convert them to degrees. As one arc minute contains sixty seconds of arc, and one degree - sixty arc minutes, seconds to degrees should be 60*60=3600.

2

Use the calculator for practical calculations because for calculation with accuracy to thousandths, it is very rare mathematical abilities. For example, it can be a standard calculator Windows. To run it click the "start" button (or press the WIN), go to menu in the Programs section, then, in its subsection "Standard" and select "Calculator". You can do it in another way- to press the key combination WIN + R, type the command calc and press Enter.

3

Enter the number of seconds by clicking buttons in the interface of the calculator on the screen or using the keyboard. Then click the key with a slash ("slash") and enter the number 3600. Then press the equal sign and the calculator will calculate and show you the value in degrees corresponding to a predetermined number of seconds.

4

Use online calculators if for some reason a hand there is no other. For example, you can enter a query with the desired mathematical operations into Google search and it will show you the result, calculate it on your own calculator. For example, if you need to find out the value of 17 seconds in degrees, then type in Google this query: "17 / 3600". Press the search button it is not necessary.

5

Usually together with the need to count seconds and minutes, as denoted by geographic coordinates in the format degrees minutes seconds (° ' "). For example, the coordinates of the most visited places in the city of Krasnodar is 45° 01' 31" North latitude and 38° 59' 58" East longitude. To translate the longitude of the location in decimal degrees, it is necessary for the whole 38 degrees, add minute, expressed in degrees (59 / 60 = 0,983), and seconds, expressed in degrees (58 / 3600 = 0,016). If counted according to the same algorithm and the latitude coordinates in degrees would look like this: 45,025° North latitude and 38,999° East longitude.

# Advice 4: How to convert geographic coordinates

**The coordinates**of the object can be recorded in several ways: in degrees, minutes, and seconds (the old method), in degrees and minutes with decimal fraction, and in degrees with a decimal fraction (the modern version). Now used all three ways, creating a need for translation of geographic coordinates from one system to another.

You will need

- coordinates in a form of writing;
- calculator;
- - the program for translation and the computer.

Instruction

1

If you are given the coordinates in degrees with decimal fraction, convert them to degrees and minutes. First calculate the latitude. For this, the number before the comma or the point of the rewrite, it will be a number of degrees. Then the fractional part of the move to degrees: multiply it by 60. The resulting number will be the minute your latitude. Perform the same operation with the longitude of the point. Note the resulting coordinates are 12°45.32 N, 31°51.06'E.

2

The same coordinates can be converted to degrees with minutes and seconds. The whole number of degrees remains the same. First, count the number of minutes for this number after the decimal point and multiply by 60. Rewrite the integer part of the result, and fractional-n perform the same operation – multiply it by 60. In the end, you will get the value of degrees, minutes and seconds with a fractional part. Record the result in the form of 22°15'20.9916"N, 17°35'3.6338"E.

3

If you, on the contrary, it is necessary to convert the coordinates from degrees to decimals, we proceed as follows. Divide the minutes specified in decimal, 60 in the result you will get the fractional part of a number of degrees. Record the result in the form 55.755831°, 37.617673°.

4

To transform coordinates with minutes and seconds to decimal, do the following. Start from the end: first, put the seconds into minutes by dividing their value by 60. Record the result in the form of degrees and minutes specified with a decimal fraction. Then turn the minutes into degrees, also dividing them by 60. As a result, you will receive the desired coordinate value in degrees.
