Category Energy
Details A watt-hour (Wh) is a unit of energy used in the field of electricity and energy systems. It represents the amount of electrical energy consumed or produced by a device with a power capacity of one watt operating continuously for one hour. The watt-hour is commonly used to quantify the energy consumption of electrical appliances and the energy production of power plants, solar panels, and batteries.

In simpler terms:

1 watt-hour (1 Wh) = 1 watt (1 W) of power used for 1 hour.

Watt-hour can be further scaled to larger units like kilowatt-hour (kWh) and megawatt-hour (MWh), which are more commonly used for electricity supply and consumption at commercial and industrial levels.

1 kilowatt-hour (1 kWh) = 1,000 watt-hours (1,000 Wh)
1 megawatt-hour (1 MWh) = 1,000 kilowatt-hours (1,000 kWh)
