      Relation Between Kilowatt-hour (kwh) and Gigawatt-hour (GWh)

      Let me explain to you about the relation between Kilowatt-hour kwh and Gigawatt-hour (GWh) first before moving to the conversion process. Because it’s essential to grasp what these units represent.

      What is Kilowatt-hour (kwh)?

      A Kilowatt-hour is a unit of energy equivalent to the energy consumed or produced when a power of one kilowatt (kW) is sustained for a duration of one hour. Kilowatt-hour (kwh) is a unit of energy measurement which is commonly used in Electric billing, energy generation. It is a non-SI unit, although widely accepted and used commercially, especially for electrical energy (the SI unit of energy is the Joule, where 1 kWh = 3.6 megajoules). This unit specifically measures the total amount of energy transferred or used, distinct from the kilowatt which measures the rate of energy transfer .

      What is Gigawatt-hour (GWh)?

      Kilowatt-hour (kwh) is another unit of energy measurement that is used in Electricity, Power Generation. A gigawatt-hour is a unit of energy equal to the energy produced by a power of one gigawatt operating for one hour.. It is a non-SI unit, although widely accepted and used commercially, especially for electrical energy (the SI unit of energy is the Joule, where 1 kWh = 3.6 megajoules). This unit specifically measures the total amount of energy transferred or used, distinct from the kilowatt which measures the rate of energy transfer .

      How to Convert Gigawatt-hour (GWh)?

      The conversion between Kilowatt-hour (kwh) and Gigawatt-hour (GWh) follows a simple formula:

      Kilowatt-hour = Kilowatt-hour × 0.000001

      Where, 0.000001 is the value that allows you to convert between Kilowatt-hour (kwh) and Gigawatt-hour (GWh).

      So,

      1 Gigawatt-hour = 0.000001 Kilowatt-hour

      And, 1 Kilowatt-hour = 1/0.000001 Gigawatt-hour

      Examples of Converting Kilowatt-hour (kwh) to Gigawatt-hour (GWh)

      To convert any value from Kilowatt-hour (kwh) to Gigawatt-hour (GWh), simply multiply the amount of Kilowatt-hour (kwh) by the conversion factor:

      1 Gigawatt-hour = 0.000001 Kilowatt-hour

      For example, if you want to convert 5 Kilowatt-hour into Gigawatt-hour and the conversion factor is 0.000001, then:

      5 Kilowatt-hour = 5 x 0.000001 Gigawatt-hour
