Fahrenheit to Celsius Conversion Guide

Temperature conversions are used every day in weather forecasts, cooking, travel, science, and medicine. One of the most common conversions is Fahrenheit to Celsius.

If you live in the United States, you probably use Fahrenheit. Most other countries use Celsius. Understanding how to convert between the two systems can help you better understand temperatures around the world.

How to Convert Fahrenheit to Celsius

Use this formula:

Celsius = (Fahrenheit - 32) × 5 ÷ 9

This formula subtracts 32 from the Fahrenheit temperature and then multiplies the result by 5/9.

Examples

• 32°F = 0°C
• 50°F = 10°C
• 68°F = 20°C
• 77°F = 25°C
• 86°F = 30°C
• 104°F = 40°C
