# How Do You Calculate kWh vs. kW ?

Let’s use a 1500W dishwasher you use for two hours per day as an example for calculating kW and kWh on a monthly basis:

1. Divide the wattage by 1,000 to calculate kW: 1500 watts / 1,000 = 1.5 kW
2. Multiply the kilowatts by the hours of daily use: 1.5 kW X 2 hours = 3 kWh per day
3. Find the total energy usage for a month (30 days): 3 kWh X 30 days = 90 kWh per month

For this example, we’ll say it’s \$.07 per kWh:

• 90 kWh X \$.07 per kWh = \$6.30 per month

A kilowatt is simply a measure of how much power an electric appliance consumes—it’s ­­1,000 watts to be exact. You can quickly convert watts (W) to kilowatts (kW) by diving your wattage by 1,000:

1,000W / 1,000 = 1 kW.

Now that you have a better understanding of kW versus kWh, and the different uses of electricity, you can take a closer look at your bill and begin to analyze your energy consumption. For a more detailed...

A kilowatt-hour measures the energy an appliance uses in kilowatts per hour. For example, if you clean your floors with a 1,000-watt vacuum cleaner for one hour, you consume 1 kWh of energy.
