0 °F in Celsius
−17.78 °C
How it is calculated
Formula: °C = (°F − 32) × 5/9 (that is, − 32, then ÷ 1.8)
- Subtract 32: 0 − 32 = −32.
- Multiply by 5/9 (divide by 1.8): −32 ÷ 1.8 = −17.7778 °C.
What this means
- Home freezers should be set to 0 °F (−18 °C) or colder (FDA).
- As outdoor weather, this is below freezing: water turns to ice and roads can be slick.
