Key Formulas
Celsius → Fahrenheit
°F = f(°C)Fahrenheit → Celsius
°C = f(°F)Celsius → Kelvin
K = f(°C)Kelvin → Celsius
°C = f(K)Formula
K = °C + 273.15Kelvin is the SI standard for temperature in physics, chemistry, and engineering. It's an absolute scale starting at absolute zero (the lowest possible temperature). Unlike Celsius and Fahrenheit, Kelvin has no negative values and no degree symbol.
