- Add 32.
- Example: 10 °C × 1.8 = 18; + 32 = 50 °F.
Where this comes up
Multiply by 9/5 and add 32. Body temperature is the top reason: 37 °C is 98.6 °F and a 38 °C fever is 100.4 °F. Oven settings are the other: 180 °C is 356 °F (US recipes say 350). −40 is the one temperature that is the same on both scales. Quick estimate: double the Celsius and add 30.
