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: -8 − 32 = -40.
Multiply by 5/9: -40 × 5/9 = -22.22 °C.

Fahrenheit to Celsius table

Fahrenheit	Celsius
-12 F	-24.44 C
-11 F	-23.89 C
-10 F	-23.33 C
-9 F	-22.78 C
-8 F	-22.22 C

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°.
