Celsius to Fahrenheit formula
°F = (°C × 9/5) + 32Celsius and Fahrenheit both measure temperature but use different reference points. The Celsius scale bases 0 °C on water's freezing point, while Fahrenheit sets 32 °F at the same point. The conversion formula °F = (°C × 9/5) + 32 comes from these offset reference points and different-sized degree increments.

Frequently asked questions
Why is the conversion formula so specific?
The formula °F = (°C × 9/5) + 32 reflects the two scales' different starting points and unit sizes. Water freezes at 0 °C but 32 °F, and each Celsius degree is 9/5 times larger than a Fahrenheit degree.
Is there a quick mental math trick for rough conversions?
Double the Celsius temperature, subtract 10%, then add 32 for a close estimate. For example, 20 °C ≈ (40 − 4) + 32 = 68 °F. For precise conversions, use our calculator.
At what temperature are Celsius and Fahrenheit equal?
Both scales meet at −40 degrees. At this point, −40 °C = −40 °F, making it the unique temperature where both scales show the same number.
