How it works

  1. Enter the temperature. Negative values are fine, down to absolute zero.
  2. Pick the scale you start from and the scale you want.
  3. Read the result and the formula behind it. Press Swap to convert back.

What people use it for

Questions

How do I convert Celsius to Fahrenheit?
°F = °C × 9/5 + 32. For example, 100 °C × 9/5 + 32 = 212 °F. The other way: °C = (°F − 32) × 5/9.
How do I convert Celsius to Kelvin?
K = °C + 273.15. So 0 °C is 273.15 K, and 0 K is −273.15 °C.
Why does the converter refuse some values?
Nothing can be colder than absolute zero: 0 K, −273.15 °C or −459.67 °F. A lower value is physically impossible, so no result is shown.
