The calculator needs JavaScript. The tables below give the same numbers for common cases.
How it is worked out
- Subtract 32: 68 − 32 = 36.
- Multiply by 5/9: 36 × 5 ÷ 9 = 20 °C.
| Inputs | Answer |
|---|---|
| 32 | 32 °F is 0 °C. |
| 98.6 | 98.6 °F is 37 °C. |
| 350 | 350 °F is 176.67 °C. |
| 212 | 212 °F is 100 °C. |
How to use it
°C = (°F − 32) × 5/9. 68 °F − 32 = 36, × 5/9 = 20 °C. Water freezes at 32 °F (0 °C) and boils at 212 °F (100 °C) at standard sea-level pressure.
A quick estimate: subtract 30 and halve. It is close for everyday temperatures; use the calculator for the exact figure.
