Formula
Celsius = (Fahrenheit − 32) × 5/9. Subtract 32 first, then multiply by 5/9.
How it works
Enter a Fahrenheit temperature. The calculator removes the 32-degree offset and rescales Fahrenheit degrees to Celsius degrees. Body temperature, about 98.6 °F, comes out near 37 °C.
FAQs
What is 32 °F in Celsius?
32 °F equals 0 °C, the freezing point of water.
What is 212 °F in Celsius?
212 °F equals 100 °C, the boiling point of water at standard pressure.
Why subtract 32 first?
Because the Fahrenheit freezing point is 32, not 0 — the offset must be removed before scaling, or the result will be wrong.
