mAh to Wh conversion calculator

Electric charge in milliamp-hours (mAh) to energy in Watt-hours (Wh) calculator.

Enter the electric charge in milliamp-hours (mAh) and voltage in volts (V) and press the Calculate button:

Enter charge in milliamp-hours:		mAh
Enter voltage in volts:		V
Energy result in watt-hours:		Wh

milliamp-hours to watt-hours calculation

So The energy E_(Wh) in watt-hours is equal to the electric charge Q_(mAh) in milliamp-hours times the voltage V_(V) in volts (V) divided by [1000].

E_(Wh) = Q_(mAh) × V_(V) / 1000

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

watt-hours = milliamp-hours × volts / 1000

or

Wh = mAh × V / 1000

Example: 1

Calculate the Watts Hours of a battery having 100Mah and 5V?

Solution:

Watt Hour = ( 100 × 5 ) / 1000
= 0.5Wh

Example: 2

Calculate the Watts Hours of a battery having 500Mah and 5V?

Solution:

Watt Hour = ( 500 × 5 ) / 1000
= 2.5Wh

Example: 3

Calculate the Watts Hours of a battery having 5000Mah and 5V?

Solution:

Watt Hour = ( 500 × 5 ) / 1000
= 25Wh

Example: 4

Calculate the Watts Hours of a battery having 10000Mah and 5V?

Solution:

Watt Hour = ( 10000 × 5 ) / 1000
= 50Wh
