Frequently asked questions
Multiply the Celsius value by 9/5 and add 32. Example: 20 °C × 9/5 + 32 = 68 °F.
Absolute zero is 0 Kelvin, or −273.15 °C (−459.67 °F). At this point, particles have the minimum thermal energy permitted by quantum mechanics.
Pure water boils at 100 °C (212 °F or 373.15 K) at sea level. At higher altitudes, the boiling point is lower due to reduced atmospheric pressure.
A healthy body temperature is around 37 °C, which equals 98.6 °F. A fever is generally considered to begin at 38 °C (100.4 °F).
