How to Convert Fahrenheit to Celsius

The fahrenheit and celsius are both units of temperature measurement. To convert fahrenheit to celsius, use the formula °C = (°F - 32) × 5/9.

Formula

°C = (°F - 32) × 5/9

Step-by-Step Example

Convert 100 °F to celsius:

1
Convert 100 °F to celsius

Formula: °C = (°F - 32) × 5/9

2
Subtract 32

100 - 32 = 68

3
Multiply by 5/9

68 × 5/9 = 37.777777778

Answer

100 °F = 37.777777778 °C

About These Units

Fahrenheit (°F)

Fahrenheit (°F) is the temperature scale used in the United States for weather, cooking, and daily life. Water freezes at 32°F and boils at 212°F. To convert Fahrenheit to Celsius: °C = (°F - 32) × 5/9. Normal body temperature is 98.6°F. Named after German physicist Daniel Fahrenheit.

Celsius (°C)

Celsius (°C), also called centigrade, is the metric temperature scale used by most countries worldwide. Water freezes at 0°C and boils at 100°C at standard pressure. To convert Celsius to Fahrenheit: °F = (°C × 9/5) + 32. Normal body temperature is 37°C. Named after Swedish astronomer Anders Celsius.
