About Energy Units

Energy is the capacity to do work and is measured in various units depending on the field:

  • Joule (J): The SI unit of energy, work, and heat.
  • Calorie (cal): The energy needed to raise the temperature of 1g of water by 1°C.
  • Kilowatt-hour (kWh): Commonly used for electrical energy billing.
  • Electronvolt (eV): Used in atomic and nuclear physics.
  • British Thermal Unit (BTU): Common in heating and cooling systems.

Energy conversion is important in many applications, from physics and engineering to everyday calculations for power consumption.
