How to convert −11 °C to Fahrenheit
−11 × 1.8 = −19.8
−19.8 + 32 = 12.2 °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: −11 × 2 + 30 = 8 °F, which is 4.2 degrees low — good for weather, not for cooking or medicine.
Careful with temperature changes: a rise of 11 °C is a rise of 19.8 °F — multiply by 1.8 but do not add 32.
What −11 °C means outdoors
At 12.2 °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 | −16 °C | 2 °F | Dress in layers |
| 20 km/h | −19 °C | −2 °F | Cover exposed skin |
| 40 km/h | −22 °C | −8 °F | Cover exposed skin |
