      Relation Between Megawatt-hour (MWh) and Watt-hour (Wh)

      Let me explain to you about the relation between Megawatt-hour MWh and Watt-hour (Wh) first before moving to the conversion process. Because it’s essential to grasp what these units represent.

      What is Megawatt-hour (MWh)?

      A megawatt-hour is a unit of energy equal to the energy produced by a power of one megawatt operating for one hour. Megawatt-hour (MWh) is a unit of energy measurement which is commonly used in Electricity, Power Generation. Megawatt-hours are commonly used in the electricity industry to measure the amount of electricity generated and consumed by large consumers, such as factories and utilities..

      What is Watt-hour (Wh)?

      Megawatt-hour (MWh) is another unit of energy measurement that is used in Electricity, Power Measurement. A watt-hour is a unit of energy equal to the energy produced by a power of one watt operating for one hour.. Megawatt-hours are commonly used in the electricity industry to measure the amount of electricity generated and consumed by large consumers, such as factories and utilities..

      How to Convert Watt-hour (Wh)?

      The conversion between Megawatt-hour (MWh) and Watt-hour (Wh) follows a simple formula:

      Megawatt-hour = Megawatt-hour × 1000000

      Where, 1000000 is the value that allows you to convert between Megawatt-hour (MWh) and Watt-hour (Wh).

      So,

      1 Watt-hour = 1000000 Megawatt-hour

      And, 1 Megawatt-hour = 1/1000000 Watt-hour
