Unit definitions

Kelvin

Kelvin is the standard unit of thermodynamic temperature in the International System of Units (SI). Kelvin generally has no negative values as it starts at absolute zero, which is the lowest temperature theoretically possible.

Celsius

Celsius is defined by the temperatures at which water freezes ($0 \ \text{°C}$) and boils ($100 \ \text{°C}$) at standard atmospheric pressure. Temperature in Celsius is equal to $\text{K} - 273.15$.

Fahrenheit

Fahrenheit is a scale commonly used in the United States. Temperature in $^{\circ}\text{F}$ is equal to $\text{K} \times \frac{9}{5} - 459.67$.

Rankine

Rankine is a scale used in engineering systems in the United States. Temperature in $^{\circ}\text{R}$ is equal to $\text{K} \times \frac{9}{5}$.
