About degrees Fahrenheit and degrees Celsius
Subtract 32 first, then multiply by 5/9 — doing it in the other order is the most common mistake. Water freezes at 32 °F (0 °C) and boils at 212 °F (100 °C), a 180-degree span that maps onto 100 Celsius degrees.
Frequently asked questions
- What is the formula to convert Fahrenheit to Celsius?
- °C = (°F − 32) × 5/9. For example, 72 °F works out to 22.22 °C.
- How do I convert 72 degrees Fahrenheit to degrees Celsius?
- Apply °C = (°F − 32) × 5/9 to 72 °F: the result is 22.22 °C.
- What's a quick way to estimate Celsius from Fahrenheit?
- Subtract 30 and halve it. 70 °F estimates to 20 °C against an exact 21.1 °C — close enough for weather, not for cooking or medicine.
