Kilowatt-hour

A kilowatt-hour (kWh) is a unit of energy commonly used to measure electricity consumption. It represents the amount of energy used when one kilowatt (kW) of power is consumed over one hour. Think of it as a way to quantify how much electricity you've used; for example, a 100-watt light bulb (which is 0.1 kilowatt) running for 10 hours uses one kilowatt-hour of energy. Utility bills typically charge based on the number of kilowatt-hours consumed, helping you understand and manage your electricity usage efficiently.
