Watt-hours to Milliamp-hours conversion

Watt-hours (Wh) to Milliamp-hours (mAh) electric charge conversion calculator and how to convert.

Enter the energy in watt-hours (Wh), the voltage in volts (V) and press the Calculate button:

Wh
V
mAh

Watt-hours to Milliamp-hours calculation formula

The electric charge Q(mAh) in milliamp-hours (mAh) is equal to 1000 times the energy E(Wh) in watt-hours (Wh) divided by the voltage V(V) in volts (V):

Q(mAh) = 1000 * E(Wh) / V(V)

So milliamp-hours is equal to 1000 times watt-hours divided by volts:

Milliamp-hours = 1000 * Watt-hours / Volts

or

mAh = 1000 * Wh / V
