How to Convert Celsius to Fahrenheit
Temperature: °C ↔ °F.
The formulas
Celsius to Fahrenheit: °F = (°C × 9⁄5) + 32
Fahrenheit to Celsius: °C = (°F − 32) × 5⁄9
Examples
- 0 °C = 32 °F (water freezes)
- 100 °C = 212 °F (water boils)
- 37 °C = 98.6 °F (body temperature)
- 72 °F = (72 − 32) × 5⁄9 ≈ 22.2 °C
Quick approximations
For a rough °C → °F: double the Celsius and add 30 (e.g. 20 °C → 20×2+30 = 70 °F; actual 68 °F). For °F → °C: subtract 30 and halve (e.g. 70 °F → (70−30)/2 = 20 °C).
