Questions fréquentes
›How do I convert Fahrenheit to Celsius?
Subtract 32 from °F, then multiply by 5/9. So 100 °F = (100 − 32) × 5/9 ≈ 37.8 °C. Or just type it here.
›What is absolute zero in each scale?
Absolute zero is 0 K = −273.15 °C = −459.67 °F = 0 °R. The Kelvin and Rankine scales start from there.
›Why is the formula different from other unit converters?
Temperature scales have different zero points (0 °C ≠ 0 °F), so conversion needs both a multiplier and an offset rather than a simple multiply.
›What temperature is normal body heat?
Roughly 37 °C, 98.6 °F or 310.15 K — though it varies by individual and time of day.
›Is the converter free?
Yes, fully free with no signup, no ads, and no data sent anywhere.
