Conversion from Kilowatt-hour to Calorie
This conversion factor holds because both units are expressed in the same base unit, the joule. Dividing the energy value in joules for one unit by the energy value in joules for the other provides the direct conversion ratio.
Definition
A kilowatt-hour (kWh) is a unit of energy equal to the energy consumed by a power of one kilowatt operating for one hour. A calorie (cal) is a unit of energy defined as the amount of heat energy needed to raise the temperature of one gram of water by one degree Celsius.
Principle
The conversion is derived by expressing both units in terms of the joule. One kilowatt-hour is defined as 3,600,000 joules, and one calorie is defined as 4.184 joules. The conversion factor is found by dividing these values.
Assumptions
- The kilowatt-hour is defined as exactly 3,600,000 joules.
- The calorie is the thermochemical calorie, defined as exactly 4.184 joules.
Cautions
- The calorie unit can have different definitions (e.g., the International Steam Table calorie); this conversion uses the thermochemical calorie.
- Rounding should be applied as required by the specific calculation.
