Temperature Conversion Table - Kelvin, Celsius, Fahrenheit

You probably don't have a thermometer that has Kelvin, Celsius, and Fahrenheit all listed, and even if you did, it wouldn't be helpful outside of its temperature range. What do you do when you need to convert between temperature units? You can look them up on this handy chart or you can do the math using simple weather conversion equations.

Temperature Unit Conversion Formulas

There's no complicated math required to convert one temperature unit to another.

Simple addition and subtraction will get you through conversions between the Kelvin and Celsius temperature scales. Fahrenheit involves a bit of multiplication, but it's nothing you can't handle. Just plug in the value you know to get the answer in the desired temperature scale using the appropriate conversion formula:

Kelvin to Celsius: C = K - 273 (C = K - 273.15 if you want to be more precise)

Kelvin to Fahrenheit: F = 9/5(K - 273) + 32 or F = 1.8(K - 273) + 32

Celsius to Fahrenheit: F = 9/5(C) + 32 or F = 1.80(C) + 32

Celsius to Kelvin: K = C + 273 (or K = C + 271.15 to be more precise)

Fahrenheit to Celsius: C = (F - 32)/1.80

Fahrenheit to Kelvin: K = 5/9(F - 32) + 273.15

Remember to report Celsius and Fahrenheit values in degrees. There is no degree using the Kelvin scale.
