How to convert 107 °F to Celsius
°C = (°F − 32) × 5/9
(107 − 32) × 5/9 = 75 × 5/9 = 375/9 = 41.67 °C
(107 − 32) × 5/9 = 75 × 5/9 = 375/9 = 41.67 °C
Subtract 32 first because the two scales put zero in different places, then multiply by 5/9 because a Fahrenheit degree is only 5/9 the size of a Celsius degree. 75 is not a multiple of 9, so the exact answer is the repeating decimal 41 2/3 °C.
Estimate it in your head
Subtract 30 and halve: (107 − 30) ÷ 2 = 38.5 °C. That is 3.2 degrees low — the shortcut drifts at very hot and very cold temperatures, so use the exact formula there.
107 °F: extreme heat and hot water
- Extreme heat. Air at 107 °F (41.67 °C) is dangerous even in dry climates; desert cities in the Southwest reach these readings on the hottest summer afternoons. Even at low humidity the heat index is high:
| Relative humidity | Heat index | NWS category |
|---|---|---|
| 10% | 101 °F | Extreme caution |
| 25% | 111 °F | Danger |
| 40% | 127 °F | Extreme danger |
- Too hot for a hot tub. 107 °F is above the 104 °F (40 °C) maximum the CPSC sets out for spa water, and well above any safe body temperature.
- Food safety. 107 °F is still inside the 40–140 °F “danger zone” where bacteria grow fastest, so food kept warm at 107 °F is not being held safely.
