How to convert Milliwatt-hours to Megawatt-hours

1 Milliwatt-hours (mWh) is equal to 1e-9 Megawatt-hours (MWh).

1 mWh = 1e-9 MWh
or
1 MWh = 1000000000 mWh

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 $10^{-3}$ . 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 $10^{-3}$ is representing Milli prefix in mWh unit.

1 mWh = 10^{-3}*Pt = 10^{-3}*IVt = 3600 * 10^{-3}*J = 2.247 * 10^{22} * 10^{-3} eV = 8.598*10^5 * 10^{-3} cal

$P - Power$
$t - Time \text{ (in hours. Multiply by 3600 to convert to seconds)}$
$I - Current$ $V - Volts$
$J - Joules$
$eV - Electronvolt$
$cal - Calories$

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 $10^6$ . 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 $10^6$ is representing Mega prefix in MWh unit.

1 MWh = 10^6*Pt = 10^6*IVt = 3600 * 10^6*J = 2.247 * 10^{22} * 10^6 eV = 8.598*10^5 * 10^6 cal
