How to Convert Fahrenheit to Celsius
The formula to convert Fahrenheit to Celsius is: °C = (°F − 32) × 5/9. Or equivalently: °C = (°F − 32) ÷ 1.8. For a quick mental estimate, subtract 30 from the Fahrenheit temperature and divide by 2 — this gives a rough approximation accurate to within a few degrees.
Key reference points: 32°F = 0°C, 50°F = 10°C, 68°F = 20°C, 98.6°F = 37°C, 212°F = 100°C. Common weather conversions: 60°F = 15.6°C, 70°F = 21.1°C, 80°F = 26.7°C, 90°F = 32.2°C, 100°F = 37.8°C. The US uses Fahrenheit for weather, cooking and body temperature, while the rest of the world uses Celsius.
