# Fahrenheit

Written by Jerry Ratzlaff. Posted in Thermodynamics

Fahrenheit is a unit of temperature used in the United States and a few other countries.  Celsius is most commonly used through the world.

## formula

$$T_{°F}=32° \;+\; \left( \frac{9}{5} \right) T_ {°C} \;$$

$$T_{°F}=459.67° \;-\; \left( \frac{9}{5} \right) T_ {°K} \;$$

$$T_{°F}= 459.67° \;-\; T_ {°R} \;$$

Where:

$$T$$ = temperature

$$C$$ = celsius

$$F$$ = fahrenheit

$$K$$ = kelvin

$$R$$ = rankine
