What is Energy?
Energy is the capacity of a physical system to do work or produce heat. The SI unit is the joule (J), defined as the work done when a force of one newton is applied over one meter (1 J = 1 N·m = 1 kg·m²/s²). Other important units include the kilowatt-hour (kWh)—used on electricity bills (1 kWh = 3.6 MJ)—the calorie (cal)—used in nutrition (1 food Calorie = 1 kcal = 4,184 J)—and the electronvolt (eV), used in atomic and particle physics (1 eV = 1.602 × 10⁻¹⁹ J).
What is Femtojoule?
Femtojoule (symbol: fJ) is a metric unit of energy equal to one quadrillionth (10-15) of a joule. It is commonly used in optical communications, microelectronics, photonics, and nanotechnology to measure extremely small energy levels. Learn more about femtojoule.
What is Kilowatt-hour?
Kilowatt-hour (symbol: kWh) is a unit of energy equal to the energy consumed by one kilowatt of power operating for one hour. One kilowatt-hour is exactly equal to 3.6 megajoules, or 3,600,000 joules. It is the standard unit used by electricity providers for measuring residential, commercial, and industrial electrical energy consumption. Learn more about kilowatt-hour.
