How to convert −24 °C to Fahrenheit
−24 × 1.8 = −43.2
−43.2 + 32 = −11.2 °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: −24 × 2 + 30 = −18 °F, which is 6.8 degrees low — good for weather, not for cooking or medicine.
Careful with temperature changes: a rise of 24 °C is a rise of 43.2 °F — multiply by 1.8 but do not add 32.
What −24 °C feels like
−24 °C is −11.2 °F. That is 6.0 degrees colder than a home freezer at −18 °C (0 °F). Environment Canada and the US National Weather Service both warn that frostbite can develop within 30 minutes once the wind chill reaches about −28 °C (−18 °F).
| Wind | Feels like | In °F | Note |
|---|---|---|---|
| 10 km/h | −32 °C | −26 °F | Frostbite possible in 30 min or less |
| 20 km/h | −36 °C | −32 °F | Frostbite possible in 30 min or less |
| 40 km/h | −39 °C | −39 °F | Frostbite possible in 30 min or less |
