Common Scenarios
Energy conversion is widely used in energy trading, nutrition, and engineering thermodynamics. In nutrition, we often look at food labels converting between kilocalories (kcal) and kilojoules (kJ). On electricity bills, kilowatt-hours (kWh) are the billing unit.
History & Background
The concept of energy took a long time to form. Later, James Joule proved through his "mechanical equivalent of heat" experiment that heat and work are interconvertible, leading to the energy unit "joule" named after him.
Conversion Details
Energy conversion is based on the joule (J), covering work, heat and electrical energy.
Common conversions: 1 kcal = 4.184 kJ, 1 kWh = 3.6 MJ, 1 BTU ≈ 1,055 J.
