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 Gigajoule?
A gigajoule (symbol: GJ) is an SI-prefixed unit of energy equal to 1,000,000,000 joules (109 J). The prefix giga- denotes one billion times the base unit. Gigajoules are widely used in energy engineering, power generation, construction, industrial processes, and environmental studies to express large quantities of energy in a compact and standardized form.
One gigajoule is equivalent to 1,000 megajoules, 1,000,000 kilojoules, or approximately 277.78 kilowatt-hours (kWh). Because many industrial and commercial energy systems involve billions of joules, the gigajoule provides a practical unit for reporting energy production, fuel consumption, and heat transfer.
Gigajoules are commonly used to measure the energy content of natural gas, coal, biomass, and other fuels, as well as the energy consumed by buildings, industrial facilities, and district heating systems. As an SI-prefixed multiple of the joule, the gigajoule ensures consistent energy measurements across scientific, engineering, and commercial applications.
What is Yoctojoule?
Yoctojoule (symbol: yJ) is a metric unit of energy equal to one septillionth (10-24) of a joule. It is used primarily in theoretical physics, quantum mechanics, and scientific research involving extremely small energy values.
