1 kWh equals about
860,42 kcal
The kilowatt-hour (kWh) is the standard electrical unit, while the kilocalorie (kcal) is the traditional thermal unit also used in nutrition. Since 1 kWh = 3,600,000 J and 1 kcal = 4,184 J, one kWh equals about 860.42 kcal.
To convert a measurement from kWh to kcal, simply multiply the value by 860.42:
To convert from kcal to kWh, perform the inverse operation, dividing by 860.42:
This conversion is interesting from an educational standpoint for comparing electrical energy with food energy on the same scale, for example to illustrate how much electrical energy would theoretically be equivalent to a person's daily caloric needs, a comparison often used to make the concept of energy more intuitive.
