## Milliampere Hours to Watt Hours Conversion Calculator

It is a conversion calculator that is used to convert the milliamp-hours (mAh) and voltage in volts to watt-hours (Wh). It has two text fields with the Calculate and Reset Buttons.The first step of using the converter is to enter the charge in milliamps-hours in the top text field. You will then enter the voltage in volts before clicking the Calculate button. The energy results in watt-hours are indicated below the two buttons. For example, if you entered the energy charge in milliamp-hours as (20 mAh) and voltage in volts as 10 (V) then your power result in watt-hours will be 0.2 (Wh).

The conversions are made easier with the Calculate button. It converts the quantity in milliamp-hours and Volts to watt-hours within a single click. The calculator has been programmed to work within seconds in delivering the accurate information.

It is important to know that the calculator only gives the output according to the units entered in the text fields. The voltage in volts text field cannot be left blank since the calculator needs both units in performing the calculation. Therefore, it means that the charge in milliamp-hours cannot be converted to watt-hours without including the voltage in volts.

#### There are formulas which the calculator uses to perform the calculations;

##### Calculation of milliamp-hours to watt-hours

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

Watt-hours = milliamp-hours x Volts / 1000, which means that the watt-hours are calculated by multiplying the number of milliamp-hours by the volts then dividing the result by 1000.

**You can also use;**

(Wh) = mAh x V / 1000 which abbreviates the formula utilized by the calculator in executing the conversions from milliamp-hours to watt-hours.

**For example,**

If you have 150 mAh and 45 V the calculation will be;

(Wh) = 150 x 45 / 1000 = 6.75 (Wh)

The online calculators have proved to be efficient in performing different conversions within a short period. It is preferable compared to manually calculating which takes time and involves a lot of paperwork.

The reset button simplifies the calculation platform as you can erase the previous calculations all at once. Always ensure that all the text fields are filled completely and with the appropriate units to provide accurate estimates.
