About Energy Units

Energy is related to work in the same way that potential is related to kinetics, i.e. energy is the ability to do work. The systems of measurement of energy are joules (SI), calories (metric) and British thermal units (English)..

  • Joule (J) is the SI unit of energy.
  • Watt-hour (Wh) and Kilowatt-hour (kWh) are the standard units of electrical energy.
  • Calorie (cal) and Kilocalorie (kcal) are used in food energy.
  • The electron volt (eV) is used in atomic physics.
  • BTU and Foot-pound force are the classical units of measurement for thermal energy and mechanical systems.

Energy Units

Knowing the energy units is the basis of energy usage in both science and daily life. Energy unit is a measurement used to know how much energy is used, produced, or transferred. The standard energy units include joules (J), calorie (cal), kilowatt-hour (kWh), and British thermal unit (BTU). The right unit for energy is the one that fits the context; e.g. in physics, the worldwide known unit is the joule, while in billing, kilowatt-hour is often used.

  • In most cases, it is required to transform energy from one unit to another. For example, when the comparison is performed between the energy produced by burning fuel and the electricity used, the conversion of energy into a common unit will ensure the correctness of the comparison. This is the point where an energy converter comes into play.
  • An energy converter unit, also referred to as an energy unit converter, is the instrument that enables the fast and accurate unit conversion of energy from one form to another. If you want an energy unit converter application or a simple table for energy units, one of these will make your unit conversion task very easy.
  • Many energy engineering, science, and management professionals are frequently involved in unit conversion energy to keep track of their calculations in the same units. In addition, you as a user can prevent any misunderstanding and errors in energy-related tasks if you know energy units well and make use of an energy converter when necessary.
