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.
