-10°C to Fahrenheit

14°F

-10°C = 14°F = 263.15 K

Working: (-10 × 9/5) + 32 = 14

-10 degrees Celsius converts to 14 degrees Fahrenheit.

To convert Celsius to Fahrenheit, multiply by 9/5 (which is 1.8) and then add 32. For -10°C: -10 × 1.8 = -18, and -18 + 32 = 14. Going the other way, subtract 32 from the Fahrenheit value and multiply by 5/9.

If you only need a rough figure, double the Celsius number and add 30 — that gives 10°F here, which is 4 degrees off the exact 14°F. The shortcut is accurate enough for weather but not for cooking or medical use.

Minus ten is a common overnight winter low across northern Europe, Canada, and the northern United States. It is also roughly where road salt starts losing effectiveness — ordinary rock salt works well down to about −9°C and poorly below it, which is why gritting advice is written around this figure.

Frequently asked questions

What is -10 degrees Celsius in Fahrenheit?

-10°C is 14°F. Multiply -10 by 1.8 to get -18, then add 32 to get 14.

What is the formula for Celsius to Fahrenheit?

°F = (°C × 9/5) + 32. Multiply the Celsius temperature by 1.8, then add 32. To reverse it, subtract 32 first and then multiply by 5/9.
