About the Kelvin Scale
The Kelvin scale is a measure of the kinetic energy of a system that assumes a starting value of absolute zero. At absolute zero, a substance would have zero kinetic energy. Because temperature is a measure of the average kinetic energy of a system, the Kelvin scale is a way of expressing temperature using only positive values. Temperatures expressed in Kelivin do not use a degree symbol because the values are absolute and not relative to the freezing point of water.
Kelvin to Celsius
- 0 K = -273.15º C
- Formula: K = °C + 273.15
- Room Temperature 20ºC = 293.15K
Kelvin to Fahrenheit
- 0 K = -459.67º F
- Formula: K = (y °F – 32) x 5/9 + 273.15
- Room Temperature 68ºF = 293.15K
