How to convert -100 °C to °F
Use the formula °F = (°C × 9/5) + 32 and substitute -100 for °C:
°F = (-100 × 9/5) + 32°F = -180 + 32°F = -148
So -100 °C = -148 °F.
What does -100 °C mean?
-100 °C is extreme cold — temperatures like this occur in polar regions, at high altitude and in laboratory or industrial settings. Exposed skin can freeze within minutes.

- Quick estimate (double + 30)
- -170 °F
For -100 °C the quick “double it and add 30” estimate gives -170 °F — 22 °F too low. The shortcut works best between about 0 °C and 20 °C; use the exact formula for anything that matters.

The Celsius to Fahrenheit formula
°F = (°C × 9/5) + 32
Multiply the Celsius temperature by 9/5 (1.8) because a Celsius degree is 1.8 times larger than a Fahrenheit degree, then add 32 because water freezes at 32 °F rather than 0 °F. To go the other way, use °C = (°F − 32) × 5/9 — for example, -148 °F back to Celsius gives -100 °C.
