# Kelvin

Written by Jerry Ratzlaff. Posted in Thermodynamics

Kelvin is a unit of temperature normally used for scientific calculations. Unlike celsius, fahrenheit and rankine, the word degree is not used. Since Kelvin starts with absolute zero it has no negative numbers.

## formula

$$T_{ °K}=273.15 °\;+\; T_ { °C}$$

$$T_{ °K}= \frac {T_ { °F} \;+\; 459.67°}{1.8}$$

$$T_{°K}= \frac {T_{ °R}} {1.8}$$

Where:

$$T$$ = temperature

$$C$$ = celsius

$$F$$ = fahrenheit

$$K$$= kelvin

$$R$$ = rankine
