Unit History
About joule
The joule is the SI unit of energy, named after James Prescott Joule for his work on the mechanical equivalent of heat. It links energy to force and distance in a single coherent framework.
About calorie
The small calorie originated in early thermodynamics to describe the heat needed to raise one gram of water by one degree Celsius. Though supplanted by joules in science, it survives in nutrition and cooking discussions.
