How to convert −10 °C to Fahrenheit
−10 × 1.8 = −18
−18 + 32 = 14 °F
Multiply by 9/5 (1.8) because each Celsius degree spans 1.8 Fahrenheit degrees, then add 32 because water freezes at 32 °F rather than 0. Since −10 is a multiple of 5, the result is a whole number.
Estimate it in your head
Double it and add 30: −10 × 2 + 30 = 10 °F, which is 4 degrees low.
Careful with temperature changes: a rise of 10 °C is a rise of 18 °F — multiply by 1.8 but do not add 32.
What −10 °C means outdoors
At 14 °F, standing water freezes and road surfaces can glaze over. Dry snow squeaks underfoot at these temperatures, and salt works more slowly on roads. With wind, it feels colder still:
| Wind | Feels like | In °F | Note |
|---|---|---|---|
| 10 km/h | −15 °C | 5 °F | Dress in layers |
| 20 km/h | −18 °C | 0 °F | Dress in layers |
| 40 km/h | −21 °C | −5 °F | Cover exposed skin |
