Fahrenheit To Celsius Formula
The calculator above uses the following formula to convert Fahrenheit to Celsius:
The worked example below shows how to convert to Celsius from Fahrenheit using this formula.
If are using this formula to manually convert a temperature, check your result with the calculator.
How To Convert Fahrenheit To Celsius (°F to °C)
This worked example shows how to convert a temperature in Fahrenheit to Celsius using the formula: Celsius (°C) = (Fahrenheit - 32) / 1.8
Worked Example
Convert 70 Fahrenheit (°F) to Celsius (°C)
| °C = | ( 70 - 32 ) / 1.8 |
| = | 38 / 1.8 |
| = | 21.11 °C |
| ∴ | therefore, 70 Fahrenheit (°F) is equal to 21.11 Celsius (°C) |
