How to convert −38 °C to Fahrenheit
−38 × 1.8 = −68.4
−68.4 + 32 = −36.4 °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: −38 × 2 + 30 = −46 °F, which is 9.6 degrees low — good for weather, not for cooking or medicine.
Careful with temperature changes: a rise of 38 °C is a rise of 68.4 °F — multiply by 1.8 but do not add 32.
What −38 °C feels like
−38 °C is −36.4 °F. That is 20.0 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 | −49 °C | −56 °F | Frostbite possible in 30 min or less |
| 20 km/h | −53 °C | −64 °F | Frostbite possible in 30 min or less |
| 40 km/h | −58 °C | −73 °F | Frostbite possible in 30 min or less |
