- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the megawatt-hour value by 1000000. This alternative method also gives you the correct energy in terawatt-hours.
- Illustration of Division:
- Terawatt-hour = mwh ÷ 1000000
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 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. Learn more about megawatt-hour.
What is Terawatt-hour?
A terawatt-hour (symbol: TWh) is a unit of energy equal to the amount of energy produced or consumed at a constant power of one terawatt for one hour. One terawatt-hour is exactly 3.6 × 1015 joules. Terawatt-hours are widely used in the electricity industry, national energy statistics, renewable energy planning, and power system analysis to express very large quantities of electrical energy.
Because one terawatt-hour represents an enormous amount of energy, it is commonly used to report the annual electricity generation or consumption of countries, regions, utility companies, and large power plants. Smaller electrical energy quantities are typically measured in watt-hours (Wh), kilowatt-hours (kWh), megawatt-hours (MWh), or gigawatt-hours (GWh).
