Kelvin, formerly called the Kelvin degree, is one of the seven basic units of measure adopted in the SI system. It is denoted by the capital letter K. In the system Degrees Kelvin starts counting from the pointAbsolute zero, corresponding to minus 273.15 degrees Celsius. Kelvin represents 1 / 273.15 part of the thermodynamic temperature of the triple point of water, however, the International Committee for Weights and Measures is currently working on changing this definition, which seems too difficult to comprehend. Soon Kelvin will be accepted to express in a second and the Boltzmann constant.

In order to translate degrees Celsius at Kelvin It is only necessary to add 273.15 to the value specified on the scale Celsius. For example, the boiling point of water equal to 100 degrees Celsius, in the Kelvin system will be equal to 100 + 273.15 = 373.15. If the calculations do not require high accuracy, tenths and hundredths of a degree can be omitted, adding to the result in Celsiusexactly 273. Translation of Kelvin into degrees Celsius The opposite is done by subtraction of 273.15 from the value given in Kelvin. So, 450,18 Kelvin can be translated into degrees Celsius As follows: 450.18 - 273.15 = 177.03.

For translate Degrees Celsius at Kelvin and for the reverse operation it is enoughcalculator. However, there is another way of translating units - using special programs that can be installed on your computer. The most popular of them is the program "Celsius - Fahrenheit - Kelvin". You can also transfer some units to others using online converters that are available on the Internet in public. Such converters usually have the ability to translate not only Kelvin, But also in such units of temperature, as, for example, the degrees of Reaumur.
Tip 2: How to convert to degrees Celsius
Degrees Celsius - the most common in most countriesscale for measuring temperature. However, in America and in Jamaica, the Fahrenheit scale is still used. In science, especially when studying ultra-low temperatures, as a rule, the Kelvin scale is applied. To convert these values to degrees Celsius There are simple formulas.
You will need
- - calculator;
- - a computer.
Instructions
1
To translate to degrees Celsius The temperature set in Kelvin, subtract from it the number 273.15. That is, use the simple formula: Тц = Тк - 273,15, where: Тц - the number of degrees Celsius, Tk is the amount of Kelvin.
2
Note that the quantity Tkwas nonnegative, and the value of T ^ was not less than -273.15 °. Violation of any of these rules clearly indicates an error in calculations or measurements.Degrees Celsius are designated as "ºС", and Kelvin - "K". The so-called "degrees of Kelvin" (ºK) is still outdated, since it has not been officially used since 1968.

If the temperature is set in degrees Fahrenheit, thenTo convert it to Celsius subtract the number 32 from the set value and multiply this difference by 5/9. If the calculation is made on a calculator, then instead of multiplying by 5/9 divide the difference by 1.8. In the form of a formula, this rule is as follows: Tc = (Tf-32) * 5/9 or Tc = (Tf-32) / 1.8, where Tf is the number of degrees Fahrenheit. The temperature measurement unit is Fahrenheit, which is denoted by ºF.

To assess the correctness of the temperature transition from degrees Fahrenheit to degrees Celsius, Be guided by the following typical indicators:+32 ° F - the melting point of the ice, +212 ° F - the boiling point of water, +100 ° F - the temperature of the human body. The fact that +100 ° F according to the formula corresponds to +37,78 ° C do not pay much attention - just a wife Fahrenheit was too hot woman ...

In order not to get confused in the calculations, use to translate the temperature to degrees Celsius Numerous on-line services, for example: www.Convertr.ru or http://2mb.ru/konverter-velichin/temperatura/. Select the name of the physical quantity (temperature), specify the specified unit of measure and enter a numerical value. An essential advantage of on-line services is not only the convenience and speed of calculation, but also the ability to translate into degrees Celsius Temperature, set on exotic temperature scales. Such, which at present are practically not used: Reaumur, Rankin, Newton, Delil, Römer.
Tip 3: How to translate from Kelvin in Celsius
The temperature is the average kineticThe energy of the particles of the system in thermodynamic equilibrium. It follows that the temperature should be measured in the energy units included in the SI system in Joules. But, historically, the temperature began to be measured long before the appearance of the molecular-kinetic theory, and in practice, conditional units-degrees are used. In the international SI system, the unit of measurement of thermodynamic body temperature is Calvin (K), which is one of the seven basic units of the system. However, in practice, most often the temperature is measured in degrees Celsius.

On a scale Kelvin The temperature is read from the absolute zero -A state in which there are no thermal vibrations completely, one degree of the scale is equal to 1 / 273.15 of the distance from absolute zero to the triple point of water. The triple point of water is a state in which ice, water and water vapor are in equilibrium. The notion of absolute temperature was introduced by W. Thomson (Kelvin), so this scale is named after his name.

In the derivative of the SI for measurementdegrees Celsius are used. The Celsius scale was proposed in 1742 by the Swedish scientist A. Celsius and is often applied in practice. This scale is tied to the main characteristics of water - the melting temperature of ice (0 ° C) and the boiling point (100 ° C). This scale is convenient because most natural processes occur precisely in this temperature range. In fact, the boiling and freezing points of water are not well defined, so the Celsius scale is determined through the scale Kelvin. Absolute zero is then defined as 0 K, which equals 273.15 ° C.

In the world there are three main measurement scalesTemperature: Celsius scale, Fahrenheit scale and Kelvin scale. The scale of Kelvin is mainly used by scientists. In most countries, a Celsius scale is used to measure temperature. For zero in the Celsius scale, the freezing point of water is adopted, and for 100 degrees the boiling point of water. This scale is used in medicine, engineering, meteorology, in everyday life. In England, the United States and some other English-speaking countries, the Fahrenheit scale is used.

One degree of Fahrenheit is 1/180 of the difference in the boiling point of water and the melting of ice. In order to convert the temperature from Fahrenheit to degrees Celsius, it's necessary from Fahrenheit temperatureSubtract 32 and the resulting value divided by 1.8. C = (F-32) / 1.8. C is the Celsius temperature, F is the temperature in degrees Fahrenheit. We give some correspondence. 0 degrees Fahrenheit corresponds to -17.8 degrees Celsius, 2. 32 degrees Fahrenheit corresponds to 0 degrees Celsius, 3. 212 degrees Fahrenheit corresponds to 100 degrees Celsius, 4. The body temperature of a healthy person is 36.6 degrees Celsius or 98.2 degrees Fahrenheit.

In order to convert the temperature from Fahrenheit to degrees Kelvin, it is necessary to add to the temperature byFahrenheit 459 and the resulting value divided by 1.8. K = (F? 32) / 1,8. K? The temperature is Kelvin. It should be noted that zero degrees Kelvin is the absolute zero temperature. Absolute zero for Kelvin is the minimum temperature that can exist. This temperature corresponds to -271.15 degrees Celsius or -459.67 degrees Fahrenheit.
Tip 5: How to translate into kelvin
In order to convert the temperature units from degrees Celsius to Kelvin, Remove the data from the thermometer and to the obtained index in degrees Celsius add the number 273.15.
You will need
- a thermometer measuring in a wide range, graduated in degrees Celsius.
Instructions
1
Take the thermometer of any system and place itSensor (it can be a bubble with a liquid, a can of gas, a bimetallic plate, a thermocouple, etc.) to the point of space where it is necessary to measure the temperature of the thermal process. For example, in order to measure the water temperature with a conventional liquid thermometer, place the bubble of the thermometer in which the colored alcohol or mercury is located directly into the water. The same is true for a gas or a solid. Determine the current temperature according to the arrows on the scale, the level of fluid in the tube, or read the digital readings on the electronic thermometer screen.
2
After the temperature in degrees Celsius is fixed, translate this value into Kelvin. For this, to the current temperature value, add the number 273.15. This is the difference between the Celsius and Kelvin temperature scales.
3
When measuring the temperature, it is necessaryobserve the safety rules in order not to get injured. Place the sensor at the point where the temperature is measured, very carefully so as not to burn yourself. The same rule applies to the measurement of ultralow temperatures. It is very important to monitor the integrity of the sensor, especially in mercury thermometers. If the bubble with mercury is cracked, the measurements should be stopped immediately, and the thermometer should be disposed of.
Tip 6: How to convert seconds to degrees
Measuring values in degrees, minutes and secondsmost often used to refer to geographic or astronomical coordinates. As in the measurement of time, each corner minute contains 60 seconds, and 60 degrees can be accommodated in a degree. This sexagesimal system of calculation has been preserved since the time of ancient Babylon. But in modern standardization systems, including the SI used in Russia, decimal calculus is used, therefore, it is often necessary to translate minutes and seconds into decimal degrees of a degree.
Instructions
1
Divide the known number of seconds by 3600 totranslate them into degrees. Since one corner corner contains sixty arc seconds, and one degree - sixty arc minutes, seconds in degrees should be 60 * 60 = 3600.
2
Use the calculator for practicalCalculations, since for calculating to within a thousandth of a fraction, very rare mathematical abilities are needed. For example, it can be a standard Windows calculator. To start it, click the "Start" button (or press the WIN key), go to the "Programs" menu, then to its "Standard" subsection and select the "Calculator" item. You can do this in another way - press WIN + R, type calc and press Enter.
3
Enter a known number of seconds by clicking the buttons in theInterface calculator on the screen or using the keyboard. Then click the slash (slash) key and enter the number 3600. Then press the equal sign and the calculator will count and show you the value in degrees corresponding to the specified number of seconds.
4
Use online calculators, if for some reasonat hand there are no others. For example, you can enter a query with the desired mathematical action into the Google search system, and it will show you the result by calculating it on your own calculator. For example, if you need to find out the value of 17 seconds in degrees, enter the following query in Google: "17/3600". You do not need to press the search button.
5
Usually, together with seconds, it is required to calculate andMinutes, since the geographical coordinates are indicated in the format "degrees of a second" (° ""). For example, the coordinates of the most visited place in the city of Krasnodar - 45 ° 01 "31" north latitude and 38 ° 59 "58" eastern longitude. To translate the longitude of this place into decimal parts of a degree, it is necessary to add the minutes expressed in degrees (59/60 = 0,983) and seconds expressed in degrees (58/3600 = 0,016) to 38 degrees. If you count by the same algorithm and latitude, the coordinates in degrees will look like this: 45,025 ° N and 38,999 ° E.
Tip 7: How to translate degrees to Kelvin in degrees Celsius
Traditionally, the temperature is measured bya device called a mercury thermometer. This tool was invented by Daniel Garriel Fahrenheit around 1715. Subsequently, different scientists proposed their temperature scales for this device. So, Anders Celsius in 1742 proposed a system that divides the freezing and boiling of water at 100 degrees, and Lord Kelvin in 1848 found the absolute minimum of temperatures, calling it the absolute zero, which is equal to - 273.15 degrees Celsius.
