How to Convert Temperatures

Converting temperatures between Fahrenheit and Celsius is simple. Here are the step-by-step guides and formulas used by our converter.

How to convert Fahrenheit to Celsius?

To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature, multiply by 5, and then divide by 9.

°C = (°F - 32) × 5/9

Example: Convert 70 degrees Fahrenheit to Celsius:

70 - 32 = 38
38 × 5 = 190
190 ÷ 9 = 21.11 °C

How to convert Celsius to Fahrenheit?

To convert Celsius to Fahrenheit, multiply the Celsius temperature by 9, divide by 5, and then add 32.

°F = (°C × 9/5) + 32

Example: Convert 20 degrees Celsius to Fahrenheit:

20 × 9 = 180
180 ÷ 5 = 36
36 + 32 = 68 °F

What is the difference between Fahrenheit and Celsius?

The Celsius scale is based on the freezing point of water (0°C) and the boiling point of water (100°C). The Fahrenheit scale sets the freezing point of water at 32°F and the boiling point at 212°F, meaning there is an exact 180-degree difference between freezing and boiling points.
