Definition of Temperature

Temperature is the measure of the average kinetic energy of molecules in an object.

Absolute Temperature Scale

Kelvin is the temperature unit named after the Irish physicist and engineer William Lord Kelvin, the inventor of the thermodynamic, absolute scale.

The scale beginning at absolute zero only has one direction, defined as 1/273.16 of the thermodynamic temperature of the triple point of water.

The Kelvin is defined as a certain fraction of the thermodynamic temperature of the triple point of water.

This fraction is 1/273.16 exactly.

The symbol for the unit and scale Kelvin is K.

Make sure to understand that in contrast to degrees Celsius, Kelvin is not referred to as degree.

The Kelvin scale is the scientific standard temperature.

Celsius Temperature Scale

The unit Celsius is also known as centigrade.

It was called so until it was renamed in honor of Anders Celsius, a Swedish astronomer, who invented the centigrade scale similar to the Celsius scale used nowadays, but which was in reverse order.

Both, the unit as well as the scale, are defined by the temperature absolute zero, and the triple point of Vienna Standard Mean Ocean Water.

Thus, Celsius is a relative scale as it can have positive and negative values.

The degree symbol or degree sign for degrees Celsius is °C.

In daily life, such as to measure the human body temperature, the Celsius scale is normally used.

Degrees Celsius and Kelvin can refer to both, a specific temperature on the scale named after its developer, as well as to the unit under consideration to indicate the difference between two temperatures or a temperature interval.

Kelvin to Celsius Formula

The Kelvin to Celsius conversion formula is as follows:

°C = K – 273.15

Try to remember this formula by the number 273.15, along with the fact that the temperature in Celsius is always 273.15 lower than measured in Kelvin.

As follows from this, the two temperatures scales don’t intersect at any point.

Convert Kelvin to Celsius

From the Kelvin to Celsius formula above we can deduct that to convert the temperature one has to subtract 273.15 from the temperature in Kelvin.

For example, to change 300 K to °C, deduct 273.15 from 300 to obtain 26.85 Celsius.

Another example of how to convert Kelvin to Celsius with 100 K:

[°C] = 100 – 273.15 = -173.15 Celsius.

Additional Information on K to C

Here we have some pieces of information about K to °C which you might want to know.

  • Kelvin is base unit in the International System of Units known as SI.
  • The unit Celsius is derived from Kelvin.
  • Kelvin is the rule in scientific temperature measurement.
  • Celsius is the standard for daily use in many countries, such as in Europe for example.
  • Absolute zero, the lowest temperature possible by the laws of thermodynamics, is defined as being precisely 0 Kelvin.
  • 1 K = 1 °C in temperature intervals. You may verify this temperature difference using the formula.
  • Absolute zero: 0 K ⇔ −273.15 °C.
  • Precise triple point of Water: 273.16 K ⇔ 0.01 °C.
  • Precise boiling point of water at 1 atm: 373.1339 K ⇔ 99.9839 °C.
