Energy and Power Converters: kWh, Joules, Calories, Watts
Energy and power are easy to mix up. Energy is an amount, such as the kilowatt hours on an electricity bill or the calories in food. Power is a rate, such as the watts of a kettle or the horsepower of a car. These converters cover the common units of both.
