What is 100° Fahrenheit in Celsius?
100°F = 37.78°C
Formula:°C = (100 - 32) × 5/9 = 68 × 5/9 = 37.78°C
Verified
- 1Subtract 32 from Fahrenheit temperature: 100 - 32 = 68
- 2Multiply by 5/9: 68 × (5 ÷ 9) = 37.7778°C (rounded to 37.78°C)
- 3Reference benchmark: Normal human body temperature is 98.6°F (37.0°C)
100° Fahrenheit equals 37.78° Celsius. To convert Fahrenheit to Celsius, subtract 32 from the temperature and multiply by 5/9.
