Joules, Kilojoules and Calories

What units are used to measure energy?
Well, that depends on who you are and what you are doing!
If you are a chemistry student, your preferred unit should be joules, but it is likely that you will have to convert between joules and kilojoules quite often.
You might also come across calories and kilocalories as a unit of measurement of energy, and you will then need to convert between these units, and between these and joules and kilojoules.

AUS-e-TUTE has set of resources to help you learn how do these conversions, and to practice your conversion skills.

There is currently a free-to-view tutorial available for evaluation purposes at:
