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 = 4.184 joules (exact)
kilo 103 (exact)
1 kWh = 3.6x106 joules (exact)
