About Fahrenheit to Celsius
Fahrenheit to Celsius conversion is essential for travelers, cooks, and scientists working with US weather data, US recipes, or US medical readings. The formula is simple, but a calculator is faster for precise values.
Formula
Celsius = (Fahrenheit − 32) × 5/9. Or: C = (F − 32) / 1.8.
Worked example
70°F − 32 = 38; 38 × 5/9 = 21.1°C. A comfortable 70°F room is about 21°C.
