How to convert energy 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.

Energy Units

The basic unit of energy is the joule. All units of energy are expressed in terms of this base unit and so measurements can be converted from any one of the following units to any other.

btu

British thermal unit: 1055.056 j

btuMean

mean BTU from 0 to 100 C: 1055.871 j

btuTh

thermochemical BTU: 1054.350 j

cal [also: calorie]

CGS unit: 4.1868 j

cal15

calorie at 15 C: 4.18580 j

cal20

calorie at 20 C: 4.18190 j

calMean

mean calorie: 4.19002 j

calNut

nutritional calorie or kilocalorie: 4186.8 j

calTh

thermochemical calorie: 4.184 j
