How 0 °C becomes 32 °F
0 °C is the freezing point of water, which the Fahrenheit scale puts at 32 °F.
0 degrees Celsius is exactly 32 degrees Fahrenheit. The formula is °F = °C × 9/5 + 32; with 0 °C plugged in it reads like this:
To check it in your head, double it and add 30: 0 °C gives about 30 °F, 2 °F below the exact 32.
Is 0 °C = 32 °F exact?
No rounding here: 0 °C is exactly 32 °F, because the definitions behind degrees Celsius and degrees Fahrenheit make this result a short decimal.

32 °F back to degrees Celsius
The other way round, 32 °F is 0 °C: (32 − 32) × 5/9 = 0 °C. The Fahrenheit to Celsius converter does this for any number.

Frequently asked questions
How many degrees Fahrenheit is 0 °C?
0 degrees Celsius is exactly 32 degrees Fahrenheit.
What is the formula for 0 Celsius to Fahrenheit?
Use °F = °C × 9/5 + 32: 0 × 9/5 + 32 = 32 °F.
What is 1 °C in degrees Fahrenheit?
1 degree Celsius is 33.8 degrees Fahrenheit, which is 1.8 °F more than 0 °C.
Is 0 °C exactly 32 °F?
Yes. 0 °C converts to 32 °F with nothing left over.
How can I check 0 °C in degrees Fahrenheit without a calculator?
Double it and add 30. For 0 °C that gives 30 °F, close to the exact 32 °F.
How do I get from 32 °F back to degrees Celsius?
Run the formula the other way: (32 − 32) × 5/9 = 0 °C. Use °C = (°F − 32) × 5/9, and you are back at 0 °C.
