Reference points
| Reference | Fahrenheit | Celsius |
|---|---|---|
| Water freezes | 32 °F | 0 °C |
| Cool day | 50 °F | 10 °C |
| Room temperature | 68 °F | 20 °C |
| Hot day | 86 °F | 30 °C |
| Normal body temperature | 98.6 °F | 37 °C |
| Fever threshold | 100.4 °F | 38 °C |
| Water boils | 212 °F | 100 °C |
A rough mental method: subtract 30 and halve it. 70 °F → 20 °C (true 21.1), 90 °F → 30 °C (true 32.2). Good enough to judge whether to take a coat, but never for body temperature or cooking, where a degree or two changes the meaning.
