What 23 °F means
- 23 °F is 9 °F below the freezing point of water (0 °C, 32 °F).
- 23 °F is 75.6 °F below the generally accepted average normal body temperature (37 °C, 98.6 °F).
- 23 °F is 189 °F below the boiling point of water at sea level, rounded to 100 °C (212 °F).
- In wind, 23 °F feels colder. Use the wind chill calculator to see how cold.
How to convert
- Subtract 32: 23 − 32 = −9.
- Multiply by 5/9: −9 × 5/9 = −5 °C.

Questions people ask
What is 23 °F in °C?
23 °F is −5 °C.
Is 23 °F above body temperature?
No. It is 75.6 °F below it. The generally accepted average normal body temperature is 37 °C (98.6 °F).
How do I estimate 23 °F in °C in my head?
Take away 30 and halve. That gives −3.5 °C. The exact value is −5 °C, so the error is 1.5 °C.
