Units of Temperature

Two units are used for temperature, degrees Centigrade and Kelvin. You need to be able to convert between the two units. To find out how to do the conversions you need to know the one fact below:

The freezing point of water is 0 °C or 273 K.
Using this information, do you think Kelvin measurements or Centigrade measurements are higher? Click on your choice.

Kelvin measurements are always higher
Centigrade measurements are always higher
Yes, you are correct. Kelvin measurements are ALWAYS HIGHER than Centigrade measurements - by 273.
No, you are wrong. KELVIN measurements are ALWAYS HIGHER than Centigrade measurements - by 273.

You can see conversions between Kelvin and Centigrade by clicking on the buttons below.



Kelvin measurements are ALWAYS HIGHER than Centrigrade measurements - by 273.

Conversion from Centigrade to Kelvin

Convert - 35 °C to Kelvin.

Kelvin is always HIGHER than the Centigrade measurement.

Thus:
ADD 273 to the Centigrade measurement.


- 35 °C = - 35 + 273 K
- 35 °C = 238 K

Conversion from Kelvin to Centigrade

Convert 297 K to degrees Centrigrade.

Centigrade is always LESS than Kelvin.

Thus:
SUBTRACT 273 from the Kelvin measurement.

297 K = 297 - 273 °C
297 K = 24 °C
