Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.

## Why do we use kilojoules?

A kilojoule (or Calorie) is a unit of energy. In Australia, we use kilojoules (kJ) to measure how much energy people get from consuming a food or drink. The kilojoule content of foods depends on the amount of carbohydrates, fats and proteins present in the food, and the portion size.

## Which is bigger kilojoules or joules?

1 Joule (J) is equal to 0.001 kilojoule (kJ). To convert joules to kilojoules, multiply the joule value by 0.001 or divide by 1000. For example, to convert 100 J to kJ, divide 100 by 1000, that makes 0.1 kJ is 100 J.
