The Fahrenheit to Celsius Formula
Use the convert degrees Fahrenheit to Celsius formula above. Subtract 32 from the Fahrenheit temperature, then multiply the result by 5/9. This adjusts for the different zero points and step sizes between the two scales.
The Celsius scale places water freezing at 0°C and boiling at 100°C. On the Fahrenheit scale, those exact points are 32°F and 212°F. That is why you first remove 32, then resize the number.
Reverse Operation
Working backward? Multiply the Celsius value by 9/5, then add 32, or just use our dedicated Celsius to Fahrenheit Converter →.

Understanding Fahrenheit and Celsius
You might wonder how to change Fahrenheit into Celsius for daily use. Fahrenheit is common for weather, body heat, ovens, and thermostats in the United States. Celsius is the standard temperature scale used by most other countries.
The two scales measure the exact same heat but use different starting points. Fahrenheit sets water freezing at 32°F and boiling at 212°F. Celsius uses 0°C and 100°C. You can easily turn Fahrenheit in to Celsius by keeping those reference points in mind.
Fahrenheit to Celsius FAQs
°C = (°F − 32) × 5/9.
°C = (°F − 32) × 5/9. For quick
mental math in your head, you can estimate by subtracting 30 and
dividing by two.
(68 − 32) × 5/9 = 20°C. This is widely considered a
comfortable room temperature.
(72 − 32) × 5/9 = 22.2°C.
(80 − 32) × 5/9 = 26.7°C.
(90 − 32) × 5/9 = 32.2°C.
(100 − 32) × 5/9 = 37.8°C. Keep in mind normal
human body temperature is slightly lower at 98.6°F or 37°C.
