Fahrenheit to Celsius
Type degrees Fahrenheit to get Celsius, or Celsius to get Fahrenheit. Results are rounded to 0.1 degree.
Temperature
Type in either box. For temperatures below zero, start with a minus sign, like -10.
How to convert Fahrenheit to Celsius
Subtract 32, then divide by 1.8. Dividing by 1.8 is the same as multiplying by 5/9.
°C = (°F − 32) ÷ 1.8 and °F = °C × 1.8 + 32Exact conversion equations from NIST Handbook 44, Appendix C and the NIST Guide to the SI, Appendix B.8.
- Subtract 32For 72 °F: 72 − 32 = 40.
- Divide by 1.840 ÷ 1.8 = 22.22…
- Round22.2 °C to one decimal.

Questions people ask
- What is the formula for Fahrenheit to Celsius?
- Subtract 32, then divide by 1.8 (the same as multiplying by 5/9). For example, (72 − 32) ÷ 1.8 = 22.2 °C.
- What is 98.6 °F in Celsius?
- (98.6 − 32) ÷ 1.8 = 37.0 °C.
- What is 350 °F in Celsius?
- (350 − 32) ÷ 1.8 = 176.7 °C. Many recipes written in Celsius round this to 175 or 180 °C.
- At what temperature are Fahrenheit and Celsius the same?
- At −40. (−40 − 32) ÷ 1.8 = −40, so −40 °F equals −40 °C.
