How to Convert Fahrenheit to Celsius
Formula
°C = (°F - 32) × 5/9
Step-by-Step
- Take the temperature in Fahrenheit
- Subtract 32 from it
- Multiply the result by 5/9 (or divide by 1.8)
- The result is the temperature in Celsius
Example
Convert 68°F to Celsius: (68 - 32) × 5/9 = 36 × 5/9 = 20°C

About the Fahrenheit Scale
The Fahrenheit scale (°F) is a temperature scale based on one proposed by physicist Daniel Gabriel Fahrenheit in 1724. It's primarily used in the United States and its territories. On this scale, water freezes at 32°F and boils at 212°F.
About the Celsius Scale
The Celsius scale (°C), also known as centigrade, is the standard temperature scale used in most countries worldwide. It's a metric scale where 0°C is the freezing point of water and 100°C is the boiling point at sea level.
