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 Joule?
A joule (J) is the SI derived unit of energy, work, and heat. Joules measure the amount of energy transferred when a force of one newton moves an object one meter in the direction of the applied force. As the standard SI unit for energy, the joule is widely used in physics, engineering, chemistry, electricity, thermodynamics, and many other scientific disciplines.
One joule is equal to one newton meter (1 N·m), one watt-second (1 W·s), or one kilogram square meter per second squared (1 kg·m²/s²). Because a joule represents a relatively small quantity of energy, larger units such as kilojoules (kJ), megajoules (MJ), and gigajoules (GJ) are commonly used in engineering, construction, and industrial applications.
Joules are commonly used to measure electrical energy, mechanical work, heat transfer, food energy in scientific calculations, and the energy stored in batteries, fuels, and moving objects. The unit provides a consistent international standard for expressing energy across different fields.
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.
