Welcome to Kelvin to Celsius, our page about the temperature conversion from the unit of measurement and scale Kelvin, to the unit of measurement and scale Celsius. If you have simply typed K to °C in your search engine, then you have come to the right site, too. We start by giving you some background information, and then answer the common questions. Read on to learn everything about converting Kelvin to Celsius.
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 symbol for the unit and scale Kelvin is K. Make sure to understand that in contrast to degrees Celsius, the Kelvin is not referred to as degree.
In turn, Celsius or degrees Celsius, is a relative scale as it can have both, positive as well as negative values. This temperature unit formerly known as centigrade is named after the Swedish astronomer Anders Celsius who came up with a similar, but inverse scale. Nowadays the temperature unit is defined by the triple point of Vienna Standard Mean Ocean Water and the temperature absolute zero. °C is the symbol for degrees Celsius.
Kelvin to Celsius Formula
The Kelvin to Celsius formula is as follows:
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 Kelvin to Celsius 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.

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. In contrast, 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 K.
- 1 K = 1 °C in temperature intervals. You may verify this 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
