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 $\text{K} \times \frac{9}{5}$.
