Watt to kWh: Understanding the Difference

When it comes to measuring electricity, two common units of measurement are Watts (W) and Kilowatt-hours (kWh). While they are related, they measure different aspects of electricity. In this article, we'll explore the difference between Watts and kWh, and how to convert between the two.

What is a Watt (W)?

A Watt (W) is a unit of power that measures the rate at which electricity is used or produced. It represents the amount of energy transferred per unit of time. In other words, it measures the flow rate of energy. A higher wattage indicates a higher rate of energy transfer.

What is a Kilowatt-hour (kWh)?

A Kilowatt-hour (kWh) is a unit of energy that measures the total amount of electricity used or produced over a period of time. It is equal to 1,000 Watts of power used for 1 hour. Kilowatt-hours are often used to measure electricity consumption in homes and businesses.

Converting Watts to Kilowatt-hours

To convert Watts to Kilowatt-hours, you need to know the time period over which the power is used. The formula to convert Watts to Kilowatt-hours is:

kWh = W x hours / 1000


  • kWh is the energy consumption in Kilowatt-hours
  • W is the power consumption in Watts
  • hours is the time period in hours


Let's say you have a 100W light bulb that you use for 5 hours. To calculate the energy consumption in Kilowatt-hours, you would use the following formula:

kWh = 100W x 5 hours / 1000 = 0.5 kWh

This means that the 100W light bulb used 0.5 Kilowatt-hours of electricity over a period of 5 hours.

Common Conversions

Here are some common conversions from Watts to Kilowatt-hours:

  • 100W x 1 hour = 0.1 kWh
  • 500W x 2 hours = 1 kWh
  • 1000W x 4 hours = 4 kWh


In conclusion, Watts and Kilowatt-hours are two different units of measurement that are used to quantify electricity. While Watts measure the rate of energy transfer, Kilowatt-hours measure the total amount of energy used or produced over a period of time. By understanding the difference between these two units, you can accurately convert between them and make informed decisions about your electricity usage.
