QUICK ANSWER
To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9. So 32 °F = 0 °C, 70 °F = 21.1 °C, 98.6 °F = 37 °C, 212 °F = 100 °C and 350 °F (a common oven setting) = 176.7 °C, usually written 180 °C. 400 °F is 204.4 °C.
THE METHOD
How it works
°F = (°C × 9 ÷ 5) + 32; °C = (°F − 32) × 5 ÷ 9; K = °C + 273.15.

The Fahrenheit to Celsius formula
°C = (°F − 32) × 5/9. Subtract 32 first, because 32 °F is the freezing point of water (0 °C), then scale by 5/9, since a Fahrenheit degree is 5/9 the size of a Celsius degree. Example: 77 °F − 32 = 45, and 45 × 5/9 = 25 °C.
Oven settings in Celsius
US recipes give oven temperatures in Fahrenheit, rounded to 25-degree steps: 325 °F is 162.8 °C, 350 °F is 176.7 °C, 375 °F is 190.6 °C, 400 °F is 204.4 °C and 425 °F is 218.3 °C. Ovens in Europe are marked in 10 °C steps, so set 160, 180, 190, 200 and 220 °C. A fan oven runs hotter: lower the setting by about 20 °C. More in the oven temperature conversion chart.
Fever in Fahrenheit and Celsius
A reading of 100.4 °F (38 °C) or higher is generally considered a fever in adults; 102 °F is 38.9 °C and 104 °F is 40 °C. For the other direction, use the Celsius to Fahrenheit converter.
