Watt hours to mAh Calculator

It is used to convert the energy in watt hours to the electric charge in milliamp hours. Since the watt hours cannot be translated direct to milliamp hours, the voltage in volts is included during the conversion. This calculator is simple to use and requires few steps to perform the calculation.

Start by entering the energy in watt hours and the voltage in volts respectively in their appropriate text fields. Click on the ‘Calculate' button to execute the conversion. The ‘Reset' button can always be used whenever you want to perform new calculations as it erases all the data on previous estimates. Below the ‘Calculate' and ‘Reset' controls is the platform where the change result in milliamps are displayed.

The watt hours to milliamp-hours calculator can only execute a single conversion at once. The ‘Reset' control is useful in erasing the computed values in a single click which allows you to start new calculations.

The formula for calculating watt hours to milliamp hours

Q (mAh) = 1000 x E (Wh) / V (V), which means that the electric charge in milliamps is calculated by multiplying the energy in watt hours by 1000 and dividing the result by voltage in volts.

It can also be expressed as;

Milliamp-hours = 1000 x watt hours / volts or mAh = 1000 x Wh / V

For example;
If the energy in watt hours is 200 Wh and the voltage supply in volts is 100 V. What is the charge result in milliamp hours?

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

= 1000 x 200 / 100 = 2000 milliamp-hours (mAh)

This calculator has been programmed to offer speed and accuracy when converting the watt hours to milliamp hours. It is important to feed in the right values since the output depends on the values entered in the required text fields.
