How to convert 10 °F to Celsius
(10 − 32) × 5/9 = −22 × 5/9 = −110/9 = −12.22 °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. −22 is not a multiple of 9, so the exact answer is the repeating decimal −12 2/9 °C.
Estimate it in your head
Subtract 30 and halve: (10 − 30) ÷ 2 = −10 °C. That is 2.2 degrees high, close enough to decide what to wear.
What 10 °F means in everyday life
- Freezers. Home freezers should hold 0 °F (−17.8 °C), so 10 °F is 10 degrees warmer than a properly set freezer — still cold enough to keep ice solid.
- Ice. At −12.22 °C, puddles, ponds and wet roads freeze. Rock salt melts ice well near 32 °F but works more and more slowly as pavement temperatures drop into the teens and below.
- Wind chill. With wind, 10 °F feels much colder:
| Wind | Feels like | In °C | Note |
|---|---|---|---|
| 10 mph | −4 °F | −20 °C | Cover exposed skin |
| 20 mph | −9 °F | −23 °C | Cover exposed skin |
| 30 mph | −12 °F | −25 °C | Cover exposed skin |
Temperatures near 10 °F

| 8 °F | −13.33 °C | 259.82 K |
| 9 °F | −12.78 °C | 260.37 K |
| 10 °F | −12.22 °C | 260.93 K |
| 11 °F | −11.67 °C | 261.48 K |
| 12 °F | −11.11 °C | 262.04 K |
| 13 °F | −10.56 °C | 262.59 K |
| 14 °F | −10 °C | 263.15 K |
| 15 °F | −9.44 °C | 263.71 K |
Going the other way: −12 °C in Fahrenheit is 10.4 °F.
Frequently asked questions
What is 10 °F in Celsius?
10 °F is −12.22 °C: subtract 32 (−22) and multiply by 5/9.
