Energy is measured in Kilocalories (kcal) and kilojoules (kJ). If you're counting calories or comparing the calorie contents of foods, this can cause confusion.

One calorie (kcal) = 4.18 kJ
To convert from calories to kJ, multiply calories by 4.18.
For example, a medium-sized banana (118 grams) provides 105 calories (kcal). 105 x 4.18 = 439 kJ.

Even when you work out, those extra calories burned only account for a tiny part of your total energy expenditure, only around 10 to 30 percent, depending on the person. It's not nearly equal to food intake.
