What is a Kilowatt-Hour? A kilowatt-hour is a unit of measure for energy usage. It’s one kilowatt of power (1000 watts) used for one hour. It’s abbreviated as kWh. It’s not the number of kilowatts you’re using in an hour, even though that seems to make sense.
Learn what a kWh means, how to calculate electricity usage, and reduce your energy bills. Complete guide with examples, calculators, and expert tips.
kW stands for kilowatt and it’s the same as 1,000 watts. It’s a measure of how much power an appliance needs to run. For example, a 1,000 watt vacuum cleaner is also a 1 kW vacuum cleaner. A kWh stands for kilowatt hour. It’s how you measure energy use. 1 kWh is the amount of energy it takes to run a 1,000 watt appliance for an hour.
A kilowatt-hour is a unit of energy used to measure energy consumption or generation. Electricity providers use kWh to determine how much electricity you consume. If you've ever looked at or compared electricity rates, you will see that these rates are priced per kWh.
In short, kWh is a unit of measurement used to quantify electricity consumption over a period of time. It is commonly used by utilities to bill customers for their electricity usage, and is calculated based on the power rating of a device and the amount of time it has been used.
