Convert Celsius to Kelvin Formula and Example Problem 2

Celsius to Kelvin Conversion
To convert Celsius to Kelvin, simply add 273.15 to the Celsius temperature and drop the degree symbol.

Many physics and chemistry problems require you to convert Celsius to Kelvin to get an absolute temperature.

Celsius to Kelvin Formula

Convert Celsius to Kelvin using a simple formula:

K = ºC + 273.15

K is the temperature in Kelvin
°C is the temperature in Celsius

For most situations, you can drop the decimal portion of the conversion:

K = ºC + 273

Remember, the Kelvin temperature scale does not use the degree (°) symbol, just the abbreviation K.

Celsius to Kelvin Conversion Example

Example Problem:
Liquid oxygen boils at normal pressure at -182.96 °C. What is this temperature in Kelvin?

K = ºC + 273.15
K = -182.96 + 273.15
K = 90.19 K

Liquid oxygen boils at 90.19 K under normal pressure.
