How to convert megawatt-hours to gigawatt-hours

1 megawatt-hours (MWh) is equal to 1×10^-3 gigawatt-hours (GWh). Conversely, 1 gigawatt-hours (GWh) is equal to 1000 megawatt-hours (MWh).

See below section for step by step unit conversion with formulas and explanations. Please refer to the table below for a list of all the Gigawatt-hours to other unit conversions.

Step by step guide to convert megawatt-hours to gigawatt-hours

Convert base units

Here, since the units are same, we just need to convert the metric prefix

1 Mega=103Giga1\ Mega = 10^{-3} Giga

Substitute to calculate GWh

1 MWh=103GWh1\ MWh = 10^{-3} GWh

What is megawatt-hours?

A Megawatt-hour is a unit of energy and its units, MWh, are formed with W for watt and h for hour from SI unit system combined with letter M, metric prefix, for 1,000,000 or 10610^6. Its definition, in the context of electricity, is the energy of one watt power flowing for one hour.

Followings equivalent equations are identical but in different units. Please note that factor 10610^6 is representing Mega prefix in MWh unit.

What is gigawatt-hours?

A Gigawatt-hour is a unit of energy and its units, GWh, are formed with W for watt and h for hour from SI unit system combined with letter G, metric prefix, for 1,000,000,000 or 10910^9. Its definition, in the context of electricity, is the energy of one watt power flowing for one hour.

Followings equivalent equations are identical but in different units. Please note that factor 10910^9 is representing Giga prefix in GWh unit.
