Energy is the capacity to do work, and it comes in many forms including thermal, electrical, chemical, and kinetic energy. Different fields use different units to measure energy.
The SI unit of energy is the joule (J). Calories and kilocalories are commonly used in nutrition, kilowatt-hours for electricity billing, BTU in heating and cooling systems, and electronvolts in particle physics.
This converter supports all major energy units, making it useful for physics calculations, nutrition planning, energy cost analysis, and scientific research.
