A Fahrenheit to Celsius converter changes temperatures from °F to °C. Enter a value in Fahrenheit to get Celsius using C = (F − 32) × 5/9, covering queries like 100 °F to °C.
Fahrenheit and Celsius are two temperature scales. Water freezes at 32 °F (0 °C) and boils at 212 °F (100 °C). The linear formula C = (F − 32) × 5/9 converts between them.
Subtract 32 from the Fahrenheit reading, then multiply by 5/9 (about 0.556). To go the other way, use F = C × 9/5 + 32.
Use C = (F − 32) × 5/9. Subtract 32 from the Fahrenheit value, then multiply by 5/9. So 212 °F becomes 100 °C.
Water freezes at 32 °F (0 °C) and boils at 212 °F (100 °C). The formula C = (F − 32) × 5/9 maps Fahrenheit onto Celsius.
