Frequently Asked Questions

What is the formula for Celsius to Fahrenheit?
°F = (°C × 9/5) + 32. For example, 100°C = (100 × 1.8) + 32 = 212°F (the boiling point of water).
What is the formula for Fahrenheit to Celsius?
°C = (°F − 32) × 5/9. For example, 72°F = (72 − 32) × 0.5556 = 22.22°C (a comfortable room temperature).
What is Kelvin used for?
Kelvin is the SI base unit for temperature used in science and engineering. It starts at absolute zero (the coldest possible temperature). 0 K = −273.15°C = −459.67°F.
What is normal body temperature?
Normal human body temperature is approximately 37°C / 98.6°F / 310.15 K. However, normal range varies between 36.1°C and 37.2°C.
At what temperature do Celsius and Fahrenheit equal?
−40 is the same in both scales: −40°C = −40°F. This is the only point where the two scales intersect.
