Common energy conversion mistakes
-
Food 'calories' are actually kilocalories: 1 kcal = 1,000 cal. A '500-calorie' meal therefore contains 500 kcal, half a million small calories. Labels write the same thing as 'kcal' or as 'Cal' with a capital C.

The relationship is exact: 1 kWh = 3.6 MJ (3,600 kJ, because an hour has 3,600 seconds). The common slip is dividing when you should multiply: 10 kWh is 36 MJ, not 2.8. Remember the direction: kWh → MJ means times 3.6.
