How to convert °F to °C
Subtract 32 from the Fahrenheit temperature, then multiply by 5/9. 77 °F − 32 = 45, and 45 × 5/9 = 25 °C. For a rough answer in your head, subtract 30 and halve it: 80 °F is about 25 °C (exactly 26.7). The chart covers everyday reference points: 32 °F is freezing, 68–72 °F is comfortable room temperature, 98.6 °F is normal body temperature and 350 °F is the most common baking temperature.
