How to convert Kilowatt Hours to Calories

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

kWh × 860,420.6500956023 = cal

Multiply your kilowatt hours value by 860,420.6500956023 to get calories. For the reverse, divide by the same factor.
