What Are Kilowatt Hours (kWh) and Watt Hours (Wh)?

What Is a Watt (W) and a Kilowatt (kW)?

First, let’s review watts and kilowatts. A watt is a measurement of how much electricity something is using or producing.

Watt = 📏 ⚡

A kilowatt is 1,000 watts.

1kW = 1,000W

What Is a Kilowatt Hour (kWh)?

A kilowatt hour is a measurement of energy, equivalent to 1 kilowatt used or produced for 1 hour.

1kWh = 1kW for 1 hr

For example, if a solar panel system generates 10 kilowatts (10,000 watts) of power for 5 hours, it would have generated 50 kilowatt hours of energy.

10kW x 5 hrs = 50kWh

What Is a Watt Hour (Wh)?

A watt hour is a measurement of energy, equivalent to 1 watt used or produced for 1 hour.

1Wh = 1W for 1 hr

So if a TV requires 100 watts, and is turned on for 5 hours, it will have used 500 watt hours of energy.

100W x 5 hrs = 500Wh

Kilowatt Hour (kWh) Vs Watt Hour (Wh)

A kilowatt hour is simply 1,000 watt hours.

1kWh = 1,000Wh
