How to convert −12 °C to Fahrenheit
−12 × 1.8 = −21.6
−21.6 + 32 = 10.4 °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. The answer always has at most one decimal place, because multiplying a whole number by 1.8 can only leave tenths.
Estimate it in your head
Double it and add 30: −12 × 2 + 30 = 6 °F, which is 4.4 degrees low — good for weather, not for cooking or medicine.
Careful with temperature changes: a rise of 12 °C is a rise of 21.6 °F — multiply by 1.8 but do not add 32.
What −12 °C means outdoors
At 10.4 °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 | −18 °C | 0 °F | Dress in layers |
| 20 km/h | −20 °C | −5 °F | Cover exposed skin |
| 40 km/h | −23 °C | −10 °F | Cover exposed skin |
