Kelvin
Kelvin is a unit of measurement of temperature.
The freezing/melting point of water is about -273.15 K at a pressure of 1 atmosphere.
The symbol of Kelvin degrees is K.
Kelvin to Celsius conversion
0 degrees Kelvin is equal to -273.15 degrees Celsius:
0 K = -273.15 °C
The temperature T in degrees Celsius (°C) is equal to the temperature T in Kelvin (K) minus 273.15:
T(°C) = T(K) - 273.15
Example
Convert 300 Kelvin to degrees Celsius:
T(°C) = 300K - 273.15 = 26.85 °C
Kelvin to Fahrenheit conversion
The temperature T in degrees Fahrenheit (°F)is equal to the temperature T in Kelvin (K) times 9/5, minus 459.67:
T(°F) = T(K) × 9/5 - 459.67
Example
Convert 300 Kelvin to degrees Fahrenheit:
T(°F) = 300K × 9/5 - 459.67 = 80.33 °F
Kelvin to Rankine conversion
The temperature T in degrees Rankine (°R) is equal to the temperature T in Kelvin (K) times 9/5:
T(°R) = T(K) × 9/5
Example
Convert 300 Kelvin to degrees Rankine:
T(°R) = 300K × 9/5 = 540 °R
