Frequently asked questions

What is the formula to convert Fahrenheit to Celsius?

Subtract 32 from the Fahrenheit value, then multiply by 5/9. As a formula that is C = (F - 32) x 5/9. For example, 212F becomes (212 - 32) x 5/9 = 100C.

What is normal body temperature in Celsius?

Normal body temperature is about 98.6F, which converts to 37C. A reading of 100.4F (38C) or higher is generally considered a fever.

What are some common Fahrenheit to Celsius conversions?

32F is 0C (water freezes), 50F is 10C, 68F is 20C (room temperature), 98.6F is 37C (body temperature) and 212F is 100C (water boils).

How do I convert oven temperatures from Fahrenheit to Celsius?

Use the same formula. 350F is about 177C, 375F is about 191C, 400F is about 204C and 450F is about 232C. Many recipes round these to 180C, 190C, 200C and 230C.
