Kilowatt-hour (kWh): definition, example and conversion

Kilowatt-hour is an energy unit (symbol kWh or kW⋅h). One kilowatt-hour is defined as the energy consumed by power consumption of 1kW during 1 hour: 1 kWh = 1kW ⋅ 1h. One kilowatt-hour is equal to 3.6⋅10 6 joules: 1 kWh = 3.6⋅10 6 J. The energy E in kilowatt-hour (kWh) is equal to the power P in kilowatts (kW), times the time t in hours

What is a Kilowatt-Hour (kWh)? Residential Electricity & Gas

35 行 What is a Kilowatt-Hour? Residential electricity usage is measured in kilowatt-hours (kWh). One kilowatt-hour (1 kWh) is equal to the amount of energy you would use if you kept a single 1,000-watt appliance running for one hour. So, if you switched on a 100-watt light bulb, it would take 10 hours to rack up 1 kWh of energy.
