A calorie and a Joule are both units used to measure energy.  In this respect, they are similar.  One calorie is equal to about 4.2kJ, or 4.2Joules/1000.  A calorie is generally a measure of heat.

The calorie was developed before the International Standard Measurements.

A joule is the SI unit for energy, or work.  1 Joule = 1newton meter= 1 watt second.  It is the result of a force over a distance.
