Temperature Converter
Convert between 3 temperature units.
About Temperature
Temperature is the odd one out: its scales don't share a zero, so you can't convert by multiplying alone. Celsius and Fahrenheit cross at −40°, which reads the same on both. Kelvin starts at absolute zero, so 0 K is −273.15 °C. Going from Celsius to Fahrenheit means multiplying by 9/5 and adding 32 — 20 °C is 68 °F, a normal room. Converting a difference rather than a reading? Use temperature interval instead.
