About converting Kilowatt-hours to Calories
Kilowatt-hours (kWh) and Calories (cal) are both units of energy, so converting between them is a single multiplication: multiply your Kilowatt-hours figure by 860,420.65. Ten Kilowatt-hours comes to 8,604,206.5 Calories, and a hundred works out at 86,042,065.01 Calories.
Rule of thumb: going from Kilowatt-hours to Calories multiplies, so the figure always grows — one Kilowatt-hour is already 860,420.65 Calories. If your answer came out smaller, you have the conversion the wrong way round.
What is a Kilowatt-hour?
The kilowatt-hour is the unit your electricity bill is charged in, and almost the only energy unit most people meet by name. It is energy, not power: a kilowatt is a rate of use, a kilowatt-hour is the amount consumed by running at that rate for an hour. Utilities bill in kWh because that is what they actually deliver — a meter counts accumulated energy, not instantaneous demand. It is also the unit that sizes batteries. An EV pack and a home storage unit are both quoted in kilowatt-hours, so the figure tells you how much range or backup you have bought, while the kilowatt rating only says how fast it can be delivered.
What is a Calory?
The calorie is the unit most likely to be misread, because there are two of them. The small calorie — the one this converter uses — is approximately the heat needed to warm a gram of water by one degree Celsius, and it is a tiny amount of energy. The "calories" printed on food labels are not these: a food Calorie, traditionally written with a capital C, is a thousand small calories, properly a kilocalorie. So a 2,000-calorie daily diet is really about 8.4 million small calories. Several slightly different calories were defined historically; the thermochemical calorie used here is fixed at exactly 4.184 joules.
To put both in perspective: an electric car covers roughly five kilometres on a kilowatt-hour, while an apple holds roughly 95,000 small calories.
