Energy Units Introduction
Watt-hour (Wh) is a unit of energy that represents the amount of energy consumed by a device with a power of 1 watt running for 1 hour. 1 watt-hour is equal to 3,600 joules (J). It is commonly used to describe the capacity of batteries and the energy consumption of electrical appliances. For example, a 60-watt light bulb running for 1 hour will consume 60 watt-hours of energy.
Milliwatt-hour (mWh) is one-thousandth of a watt-hour, equal to 0.001 watt-hours (1 mWh = 0.001 Wh). It is commonly used to describe the energy consumption of small electronic devices, such as smartwatches or small sensors. Since these devices typically have very low energy consumption, milliwatt-hours is an appropriate unit.
Kilowatt-hour (kWh) is one thousand times a watt-hour, equal to 1,000 watt-hours (1 kWh = 1,000 Wh). This is a common unit for household and industrial electricity usage, often appearing on electricity bills. For example, a 2,000-watt heater running for 1 hour will consume 2 kilowatt-hours of energy.
Megawatt-hour (MWh) is one million times a watt-hour, equal to 1,000,000 watt-hours (1 MWh = 1,000,000 Wh). It is commonly used to describe the energy production and consumption of large power plants or industrial facilities. For example, a large wind turbine might generate several hundred megawatt-hours of electricity in a day.
Gigawatt-hour (GWh) is one billion times a watt-hour, equal to 1,000,000,000 watt-hours (1 GWh = 1,000,000,000 Wh). It is commonly used to describe very large-scale energy production and consumption, such as the annual electricity demand of a country or region.
Joule (J) is the basic unit of energy in the International System of Units (SI), representing the work done when a force of 1 newton is applied to an object and moves it 1 meter. 1 joule is equal to 1 watt-second (1 J = 1 Ws). It is widely used in physics and engineering.
Kilojoule (kJ) is one thousand times a joule, equal to 1,000 joules (1 kJ = 1,000 J). It is commonly used to describe the energy content of food and the energy changes in chemical reactions. For example, an energy bar might contain 200 kilojoules of energy.
Megajoules (MJ) is one million times a joule, equal to 1,000,000 joules (1 MJ = 1,000,000 J). It is commonly used to describe the energy consumption of large mechanical systems or industrial processes. For example, a car might consume several megajoules of energy after traveling a certain distance.
Gigajoules (GJ) is one billion times a joule, equal to 1,000,000,000 joules (1 GJ = 1,000,000,000 J). It is commonly used to describe very large-scale energy consumption and production, such as the annual energy consumption of a large factory.
