# Celsius to Kelvin | °C to K

## Calculator Use

Convert degrees Celsius to temperature in Kelvin.

## Celsius °C to Kelvin K Formula

K equals °C plus 273.15.

## How to Convert Celsius to Kelvin

- Add 273.15 to degrees Celsius

For example, to convert 21.5 degrees Celsius (centigrade) to Kelvin, we plug our numbers into the formula as shown below:

K = 21.5 + 273.15

K = 294.65

21.5 degrees Celsius is equal to 294.65 Kelvin.

This calculator will show the steps to solve the °C to K formula so you know how make the conversion yourself.

## Kelvin

Kelvin is a temperature scale and Kelvin are units of temperature on that scale. The symbol for Kelvin is K without a degree (°) symbol. On the Kelvin scale the boiling point of water is 373.15 K, the freezing point of water is 273.15 K and absolute zero is 0 K. The Kelvin scale does not contain negative values.

## Celsius

Celsius is a temperature scale and degrees Celsius are units of temperature on that scale. The symbol for degree Celsius is °C. A temperature such as 15 °C is stated "fifteen degrees Celsius". On the Celsius scale the boiling point of water is 100 °C, the freezing point of water is 0 °C and absolute zero is −273.15 °C.
