How to convert FAHRENHEIT to CELSIUS
Fahrenheit temperatures appear in American weather forecasts, US cooking recipes, oven settings, and medical references like the 98.6 F normal body temperature. If you grew up with Celsius, those numbers are meaningless without a quick conversion. The formula is: subtract 32 from the Fahrenheit value, then multiply by 5/9.
A few key landmarks to keep in mind: 32 F is 0 C (freezing point of water), 72 F is about 22 C (comfortable room temperature), 212 F is 100 C (boiling water), and 350 F is 177 C (a common oven baking temperature). BoltConverter applies the conversion instantly as you type, so you can check any value without memorizing the formula.
