How to convert −29 °C to Fahrenheit
−29 × 1.8 = −52.2
−52.2 + 32 = −20.2 °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: −29 × 2 + 30 = −28 °F, which is 7.8 degrees low — good for weather, not for cooking or medicine.
Careful with temperature changes: a rise of 29 °C is a rise of 52.2 °F — multiply by 1.8 but do not add 32.
What −29 °C feels like
−29 °C is −20.2 °F. That is 11.0 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 | −38 °C | −36 °F | Frostbite possible in 30 min or less |
| 20 km/h | −42 °C | −43 °F | Frostbite possible in 30 min or less |
| 40 km/h | −46 °C | −51 °F | Frostbite possible in 30 min or less |
