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 Millijoule?
A millijoule (symbol: mJ) is an SI-prefixed unit of energy equal to one thousandth of a joule (10−3 J). The prefix milli- denotes one thousandth of the base unit. Millijoules are commonly used in electronics, laser technology, physics, medical equipment, and laboratory research to measure small amounts of energy with precision.
One millijoule is equivalent to 0.001 joule or 1,000 microjoules (µJ). Because many scientific and engineering applications involve energy levels much smaller than one joule, the millijoule provides a convenient way to express these values without using long decimal numbers.
Millijoules are widely used to specify the energy output of laser pulses, electrical discharge devices, medical instruments such as defibrillators during testing, and precision laboratory experiments. As an SI-prefixed multiple of the joule, the millijoule offers a standardized and internationally recognized unit for measuring small quantities of energy.
What is Megawatt-hour?
Megawatt-hour (symbol: MWh) is a unit of energy equal to the energy produced or consumed by one megawatt of power operating for one hour. One megawatt-hour is exactly equal to 3.6 gigajoules, or 1,000 kilowatt-hours. The unit is widely used in electric power generation, utility operations, and large-scale energy reporting.
