How to convert -23 °C to °F

Use the formula °F = (°C × 9/5) + 32 and substitute -23 for °C:

°F = (-23 × 9/5) + 32
°F = -41.4 + 32
°F = -9.4

So -23 °C = -9.4 °F.

What does -23 °C mean?

-23 °C is very cold weather, well below the freezing point of water. It is typical of a hard winter in northern climates; warm layers, gloves and a hat are essential outdoors.

Fahrenheit: -9.4 °F
Kelvin: 250.15 K
Quick estimate (double + 30): -16 °F

For -23 °C the quick “double it and add 30” estimate gives -16 °F — 6.6 °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, -9.4 °F back to Celsius gives -23 °C.
