How to convert Kilocalories to Kilowatt Hours
Energy appears as joules in physics, calories in nutrition, and kilowatt hours on electricity bills. All measure the same thing — the capacity to do work — just at very different scales.
Everything converts through the joule. One (small) calorie is exactly 4.184 joules, a food Calorie (kcal) is 4,184 joules, and one kilowatt hour is exactly 3.6 million joules.
Formula
kcal × 0.0011622222 = kWh
Multiply your kilocalories value by 0.0011622222 to get kilowatt hours. For the reverse, divide by the same factor.
