How to convert temperature units using the AddUp calculator

How to convert units in general

Conversions can be done either with the "->" conversion operator or with the equivalent "convert" function. The function has three parameters: a quantity, a unit to convert from and a unit to convert to. Likewise the conversion operator uses three values: the quantity and unit to convert from are placed on the left side of the operator while the unit to convert to goes to the right side.

Temperature Units

AddUp expresses temperature units using complex numbers. In each complex number, the real component is one degree of the given scale expressed in Kelvin and the imaginary component is the absolute zero in the scale in question. Both Kelvin and Rankine are absolute scales so the value of their imaginary component is zero. The "convert" function and the conversion operator process these complex numbers appropriately to obtain correct temperature conversions.

C [also: Celsius, centigrade]: Celsius temperature scale: (1; -273.15)
F [also: Fahrenheit]: Fahrenheit temperature scale: (5/9; -459.67)
K [also: Kelvin]: Basic unit of temperature: (1; 0)
R [also: Rankine]: Rankine temperature scale: (5/9; 0)
Reaumur: Reaumur temperature scale: (1.25; -218.52)

Sample Conversions of Temperature Units

Convert Celsius to Fahrenheit

30 C -> F = 86

convert(30; Celsius; Fahrenheit) = 86

Convert Celsius to Kelvin

100 Celsius -> Kelvin = 373.15

convert(100; C; K) = 373.15

Convert Celsius to Rankine

0 Celsius -> Rankine = 491.67

convert(0; centigrade; R) = 491.67

Convert Fahrenheit to Celsius

0 Fahrenheit -> C = -17.777778

convert(0; F; Celsius) = -17.777778

Convert Fahrenheit to Kelvin

-30 F -> K = 238.70556

convert(-30; Fahrenheit; Kelvin) = 238.70556

Convert Fahrenheit o Rankine

80 Fahrenheit -> Rankine = 539.67

convert(80; F; R) = 539.67

Convert Kelvin to Rankine

100 Kelvin -> Rankine = 180

convert(100; Kelvin; Rankine) = 180

Convert Kelvin to Celsius

100 K -> C = -173.15

convert(100; Kelvin; centigrade) = -173.15

Convert Kelvin to Fahrenheit

100 K -> F = -279.67

convert(100; Kelvin; Fahrenheit) = -279.67

Convert Rankine to Kelvin

100 Rankine -> Kelvin = 55.555556

convert(100; R; K) = 55.555556

Convert Rankine to Reaumur

100 R -> Reaumur = -174.07556

convert(100; Rankine; Reaumur) = -174.07556

Convert Reaumur to Kelvin

100 Reaumur -> K = 398.15

convert(100; Reaumur; Kelvin) = 398.15
