What this means
At or below 32 °F water freezes. These are sub-freezing temperatures — 0 °F is about −17.8 °C, a hard winter day in cold climates.
- Water freezes = 32 °F (0 °C)
- Home freezer ≈ 0 °F (−18 °C)
The math, step by step
- Subtract 32 from the Fahrenheit value: -11 − 32 = -43.
- Multiply by 5/9: -43 × 5/9 = -23.89 °C.
Fahrenheit to Celsius table
Formula
°C = (°F − 32) × 5/9
To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature, then multiply by 5/9 (or divide by 1.8). The Fahrenheit scale sets water's freezing point at 32° and boiling at 212°, while Celsius uses 0° and 100°.
