How temperature conversion works
Temperature scales measure the same heat level using different starting points. Fahrenheit is commonly used in the United States, while Celsius is standard in much of the rest of the world.
To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9. To convert Celsius to Fahrenheit, multiply by 9/5 and add 32.
Example
If the weather forecast says 72°F and you want it in Celsius:
(72 - 32) × 5 ÷ 9 = 22.22°C
So 72°F is about 22.22°C.
Common uses
- Checking weather while traveling
- Reading recipes from another country
- Comparing room, pool, or outdoor temperatures
