How to convert −2 °F to Celsius
(−2 − 32) × 5/9 = −34 × 5/9 = −170/9 = −18.89 °C
Subtract 32 first because the two scales put zero in different places, then multiply by 5/9 because a Fahrenheit degree is only 5/9 the size of a Celsius degree. −34 is not a multiple of 9, so the exact answer is the repeating decimal −18 8/9 °C.
Estimate it in your head
Subtract 30 and halve: (−2 − 30) ÷ 2 = −16 °C. That is 2.9 degrees high, close enough to decide what to wear.
What −2 °F feels like
Below zero Fahrenheit, wind matters more than the thermometer. The National Weather Service wind chill index estimates how cold −2 °F feels on exposed skin; once the wind chill reaches about −18 °F (−28 °C), frostbite can set in within 30 minutes.
| Wind | Feels like | In °C | Note |
|---|---|---|---|
| 10 mph | −18 °F | −28 °C | Frostbite possible in 30 min or less |
| 20 mph | −25 °F | −31 °C | Frostbite possible in 30 min or less |
| 30 mph | −29 °F | −34 °C | Frostbite possible in 30 min or less |
At −18.89 °C even a home freezer (0 °F) would feel warm. Car batteries lose much of their cranking power, diesel fuel can gel without additives, and pipes in unheated spaces are at real risk.
