How to Convert Celsius to Kelvin

To convert a Celsius temparature to a kelvin temparature, use the following fomular:

What is the formula to convert from Celsius to Kelvin?

k=°C + 273.15


Convert 5°C to kelvin

5 °C = 5 + 273.15 = -278.15 k

Convert 10°C to kelvin

10 °C = 10 + 273.15 = 283.15 k

Convert 100°C to kelvin

100 °C = 100 + 273.15 = 373.15 k


What is a Celsius?

The Celsius (symbol: °C) is an SI (International System of Units) derived unit of temperature. It is defined based on the SI unit of temperature, the kelvin. The Celsius and Kelvin scales are precisely related, with a one-degree change in Celsius being equal to a one degree-change in kelvin.

What is the Celsius used for?

The Celsius scale replaced the Fahrenheit scale in most countries in the mid to late 20th century. Almost all countries around the world use this scale, except for those in which the metric system has not been adopted, such as the United States.


What is a Kelvin?

The kelvin (symbol: K) is the base unit of thermodynamic temperature in the International System of Units (SI). It is defined as the energy equivalent of the triple point of water as given by Boltzmann's equation. It is also the unit of the Kelvin scale in which the null point (0 K) is the temperature at which all thermal motion ceases, known as absolute zero.

What is the Kelvin used for?

The kelvin is used worldwide, particularly in science and engineering, together with the Celsius. This is partially due to the kelvin and the Celsius degree having exactly the same magnitude. Unlike the Celsius and Fahrenheit, the kelvin is not used in meteorological contexts.
