117 Fahrenheit to Celsius
117 degrees Fahrenheit equals
47.22°C
47.22 degrees Celsius
117°F is 47.22°C — hot to the touch. Household hot water arrives somewhere in this range; most water heaters are set near 49°C (120.2°F) to limit scalding risk.
How to convert 117°F to °C
Formula
°C = (°F − 32) × 5/9
Substituting 117°F
- 117 − 32 = 85
- 85 × 5/9 = 47.22
Fahrenheit places the freezing point of water at 32 rather than 0, so that offset comes off first. What remains is then scaled by 5/9, because a Celsius degree covers 1.8 times as much temperature change as a Fahrenheit degree.
How 117°F compares
| Reference point | Temperature | Difference |
|---|---|---|
| Freezing point of water | 0°C / 32°F | 47.2°C (85°F) warmer |
| Room temperature | 21°C / 69.8°F | 26.2°C (47.2°F) warmer |
| Body temperature | 37°C / 98.6°F | 10.2°C (18.4°F) warmer |
| Boiling point of water | 100°C / 212°F | 52.8°C (95°F) colder |
