Temperature Typical Units

Common units for temperature are as follows:

Celcius to Farenheit

\(\large{ C = 5/9 \;(F - 32) }\) 

\(\large{ F = 9/5 \;(C + 32) }\)

Celcius to Kelvin

\(\large{ K = C - 273.15 }\)

\(\large{ C = K + 273.15 }\)

Farenheit to Rankine

\(\large{ R = F - 459.67 }\)

\(\large{ F = R + 459.67 }\)

Celsius

Celsius, abbreviated as C, is a unit of temperature most commonly used through out the world.  

Celsius Formula

\(\large{ T_{°C} = \frac {T_ {°F}   \;-\;  32°}{1.8}  }\)

\(\large{ T_{°C} = 273.15° - T_ {°K} }\)

\(\large{ T_{°C} = \left( \frac {T_{°R}} {1.8} \right)  - 273.15° }\)

Where:

\(\large{ T }\) = temperature

\(\large{ C }\) = celsius

\(\large{ F }\) = fahrenheit

\(\large{ K }\) = kelvin

\(\large{ R}\) = rankine

Fahrenheit

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

Fahrenheit Formula

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

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

\(\large{ T_{°F} =  459.67° - T_ {°R}  }\)

Where:

\(\large{ T }\) = temperature

\(\large{ C }\) = celsius

\(\large{ F }\) = fahrenheit

\(\large{ K }\) = kelvin

\(\large{ R }\) = rankine

Kelvin

Kelvin, abbreviated as K, 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.

Kelvin Formula

\(\large{ T_{ °K} = 273.15 ° + T_ { °C}  }\)

\(\large{ T_{ °K} = \frac {T_ { °F} \;+\; 459.67°}{1.8}  }\)

\(\large{ T_{°K} = \frac {T_{ °R}} {1.8}  }\)

Where:

\(\large{ T }\) = temperature

\(\large{ C }\) = celsius

\(\large{ F }\) = fahrenheit

\(\large{ K }\)= kelvin

\(\large{ R }\) = rankine

Rankine

Rankine, abbreviated as R, is a unit of temperature used in the US engineering field.  0 is set at absolute zero.

Rankine Formula

\(\large{ T_{°R} = \left(273.15° + T_ { °C} \right )\; 1.8 }\)

\(\large{ T_{°R} = 459.67° + T_ { °F}  }\)

\(\large{ T_{°R} = \left( T_{°K} \right) \;1.8  }\)

Where:

\(\large{ T }\) = temperature

\(\large{ C }\) = celsius

\(\large{ F }\) = fahrenheit

\(\large{ K }\) = kelvin

\(\large{ R }\) = rankine
