Fahrenheit → Celsius
How to Convert -20°F to Celsius
To convert -20 degrees Fahrenheit to Celsius, use the standard temperature conversion formula:
Step-by-step calculation:
- Subtract 32: -20 − 32 = -52
- Multiply by 5/9 (or 0.5556): -52 × 5/9 = -28.9°C
Therefore, -20°F = -28.9°C.
-20°C (-28.9°F) — Extreme cold — dangerous conditions
Temperatures below -20°C (-4°F) are dangerously cold. Exposed skin can develop frostbite within minutes, and hypothermia risk is high.
What this feels like
Bitterly cold. Any exposed skin feels painful almost immediately. Wind chill makes it feel even colder.
Key facts
- ✓Frostbite can occur on exposed skin within 10–30 minutes at -20°C with wind
- ✓Dress in multiple insulating layers — wool or synthetic base layers, insulated mid-layer, windproof outer shell
- ✓Keep extremities (fingers, toes, ears, nose) covered at all times
- ✓Limit time outdoors; check on vulnerable people (elderly, children)
