42 °C to Fahrenheit.
42 °C = 107.6 °F.
What 42 °C means
- 42 °C is 42 °C above the freezing point of water (0 °C, 32 °F).
- 42 °C is 5 °C above the generally accepted average normal body temperature (37 °C, 98.6 °F).
- 42 °C is 58 °C below the boiling point of water at sea level, rounded to 100 °C (212 °F).
- In humid air, 42 °C feels hotter. Use the heat index calculator to see how hot.
How to convert
- Multiply by 9/5 (1.8): 42 × 1.8 = 75.6.
- Add 32: 75.6 + 32 = 107.6 °F.

Questions people ask
What is 42 °C in °F?
42 °C is 107.6 °F.
Is 42 °C above body temperature?
Yes. It is 5 °C above it. The generally accepted average normal body temperature is 37 °C (98.6 °F).
How do I estimate 42 °C in °F in my head?
Double the °C and add 30. That gives 114 °F. The exact value is 107.6 °F, so the error is 6.4 °F.
Is 42 °C a fever?
CDC guidance for reporting ill travelers counts a measured temperature of 38 °C (100.4 °F) or more as a fever. 42 °C meets that value. Ask a health care provider about a fever.
