How to convert 38 °F to Celsius
°C = (°F − 32) × 5/9
(38 − 32) × 5/9 = 6 × 5/9 = 30/9 = 3.33 °C
(38 − 32) × 5/9 = 6 × 5/9 = 30/9 = 3.33 °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. 6 is not a multiple of 9, so the exact answer is the repeating decimal 3 1/3 °C.
Estimate it in your head
Subtract 30 and halve: (38 − 30) ÷ 2 = 4 °C. That is 0.7 degrees high, close enough to decide what to wear.
What 38 °F means
- Refrigerator range. The FDA says refrigerators should run at 40 °F (4.4 °C) or colder, so 38 °F (3.33 °C) is a safe fridge temperature. Bacteria multiply quickly between 40 °F and 140 °F, the “danger zone.”
- Dress for it. 38 °F calls for a warm jacket, especially with wind; the wind chill index applies at 50 °F and below.
| Wind | Feels like | In °C | Note |
|---|---|---|---|
| 10 mph | 31 °F | 0 °C | Dress in layers |
| 20 mph | 28 °F | −2 °C | Dress in layers |
| 30 mph | 26 °F | −3 °C | Dress in layers |
