Why the kcal-to-kWh conversion factor holds
The conversion factor arises because both kilocalories and kilowatt-hours are defined in terms of the joule, the SI unit of energy. By expressing each unit in joules, a direct ratio can be calculated.
Definition
A kilocalorie (kcal) is a unit of energy defined as exactly 4,184 joules. A kilowatt-hour (kWh) is a unit of energy equal to the energy consumed by a power of one kilowatt in one hour, which is exactly 3,600,000 joules.
Principle
The conversion factor is derived by dividing the number of joules in one unit by the number of joules in the other unit. For kcal to kWh, this is 4,184 / 3,600,000.
Assumptions
- The definitions of kilocalorie and kilowatt-hour in terms of joules are exact as provided.
- The conversion uses the defined relationship without rounding to intermediate steps.
Cautions
- The conversion factor shown is a precise mathematical result based on the given definitions.
- Rounding the final result is necessary for practical use, as specified in the calculation.
