The most widespread scale of measurement of temperatures is Celsius scale used in many countries of the world. The second most popular is considered the Fahrenheit scale by which residents of the USA are guided. However when carrying out scientific calculations there is a requirement of the transfer of degrees Celsius to other units – Kelvins.

1. The kelvin which was earlier called as degree Kelvin is one of seven main units of measure accepted in the SI system. It is designated by a capital letter of K.V to the system of degrees Kelvin reckoned from a point of absolute zero, to the corresponding minus 273.15 degrees Celsius. The kelvin represents 1/273.15 part of thermodynamic temperature of a threefold point of water, however, now the International committee died and scales works on change of this definition which is represented too difficult for perception. Shortly Calvin it will be accepted to express in a second and Boltzmann's constant.
2. In order that to translatedegreesCelsius in Kelvins needs to be added only 273.15 to the value set on Celsius scale. For example, water boiling temperature, to equal 100 degrees Celsius, will be equal in Calvin's system to 100 + 273.15 = 373.15. If in calculations high precision is not required, the tenth and 100-th shares of degree can be lowered, adding to result in Tselsiyakh exactly 273. A transfer of Kelvins in degrees Celsius is made in the return way – subtraction 273.15 of the value set in Kelvins. So, 450.18 Kelvins can be transferred in degrees Celsius as follows: 450.18 - 273.15 = 177.03.
3. For transfer of degrees Celsius to Kelvins and for the return operation of rather ordinary calculator. However there is also other way of the translation of units – by means of special programs which can be installed on the computer. The most popular of them is the Celsius — Fahrenheit — Kelvin program. Also it is possible to make a transfer of some units in others by means of online converters which are on the Internet in open access. Similar converters usually have potential of the transfer not only to Kelvins, but also in such units of measure of temperature as, for example, Reaumur's degrees.
