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 Zeptojoule?
A zeptojoule (symbol: zJ) is an SI-prefixed unit of energy equal to one sextillionth of a joule (10−21 J). The prefix zepto- denotes a factor of 10−21. Zeptojoules are used in atomic physics, quantum mechanics, nanotechnology, biophysics, and materials science to describe extremely small quantities of energy that are impractical to express in whole joules.
One zeptojoule is equivalent to approximately 6.2415 millielectron-volts (meV). Because many molecular and atomic interactions involve energy on the zeptojoule scale, this unit provides a convenient way to express microscopic energy values without using long decimal numbers.
Zeptojoules are commonly encountered in research involving single molecules, quantum devices, nanoscale systems, and biological processes. As an SI-prefixed subdivision of the joule, the zeptojoule provides a standardized and internationally recognized unit for measuring extremely small amounts of energy.
What is Gigawatt-hour?
Gigawatt-hour (symbol: GWh) is a unit of energy equal to the energy generated or consumed by one gigawatt of power operating for one hour. One gigawatt-hour is exactly equal to 3.6 terajoules, or 1,000 megawatt-hours. It is commonly used to report the annual electricity production of power plants and the energy consumption of cities and regions. Learn more about gigawatt-hour.
