How to convert milliwatt-hours to kilowatt-hours

1 milliwatt-hours (mWh) is equal to 1×10^-6 kilowatt-hours (kWh). Conversely, 1 kilowatt-hours (kWh) is equal to 1×10^6 milliwatt-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 Kilowatt-hours to other unit conversions.

Step by step guide to convert milliwatt-hours to kilowatt-hours

Convert base units

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

1 Millie=10−6Kilo1\ Millie = 10^{-6} Kilo

Substitute to calculate kWh

1 mWh=10−6kWh1\ mWh = 10^{-6} kWh

What is milliwatt-hours?

A Milliwatt-hour is a unit of energy and its units, kWh, are formed with W for watt and h for hour from SI unit system combined with letter m, metric prefix, for 0.001 or 10−310^{-3}. 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 10−310^{-3} is representing Milli prefix in mWh unit.

What is kilowatt-hours?

A Kilowatt-hour is a unit of energy and its units, kWh, are formed with W for watt and h for hour from SI unit system combined with letter k, metric prefix, for 1,000 or 10310^3. 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 10310^3 is representing Kilo prefix in kWh unit.
