UnitConEnergy
Energy is measured in different units depending on the field. The SI unit is the joule, but people also encounter calories in nutrition, kilowatt-hours on electric bills, BTU in heating and cooling, and electronvolts in physics. This converter helps compare those systems while clarifying how they relate. It also notes that the food "Calorie" with a capital C is the same as one kilocalorie.
