Electrical energy is usually measured in kilowatt-hours, kWh. A Watt is 1 joule per second. A kiloWatt is 1000 joules per second. An hour has 3600 seconds. Therefore 1 kWh = 3.6x106 joules. How many kWh are there in a meal that is 776 Cal, or nutritional calories? Just put in the number. The assumption is the unit is kWh. 1 Nutritional Cal = 1 kcal (exact) 1 cal = 4184 joules (exact)
