What scales are supported?

Celsius (°C), Fahrenheit (°F), and Kelvin (K). Enter any one and get the other two.

How is Kelvin related?

K = °C + 273.15. 0 K is absolute zero. Water freezes at 273.15 K.

°F = °C × 9/5 + 32. °C = (°F − 32) × 5/9.

Convert between Celsius (°C), Fahrenheit (°F), and Kelvin (K). Enter a value and see all three scales.
