mAh to Wh Calculator

mAh is an abbreviation representing milliampere per hour, whereas Wh is an abbreviation for watts per hour. mAh and Wh are both units for measurement of power.

You can apply these measurement units when comparing the battery capacity in different electrical appliances.

When checking battery capacity, you might get confused by other measurements such as ampere-hour (Ah), Voltage(V), Watts(W), Coulombs, etc.

Proper understanding of the various standard units of measurement of power is key. The following article will look into some of the mAh to Wh conversions.

Definition of each element of the calculation

Milliampere-hour (mAh) represents battery capacity in small batteries. In large batteries, the battery capacity representation is in Ampere-hour. This difference means that 1Ah represents 1000mAh.

If you want to determine the battery capacity, you multiply the current discharge in amperes with the time the battery lasts.

For instance, if you connect your battery to a 1Ah discharge current and it lasts for 5 minutes, that means it has a battery capacity of 5000mAh.

Note that this is a very misleading unit since battery capacity expressed in mAh must have a stated voltage.

The watt-hour is not a standard unit but represents the equivalent of 1W power dissipated in an hour.

Watt-hour (Wh) is more accurate when comparing the battery capacities.

You can compare batteries using watts-hour (Wh), regardless of whether they have different voltages, unlike in milliampere-hour (mAh), where it is more accurate in comparing batteries with the same voltage.

Note that the battery capacity and output power are different concepts; hence you can find that a battery of 200Wh only has an output power of 100W.

The device’s watt-hour (Wh) represents the capacity of all the combined battery cells.

For instance, if the cell capacity is 3.5Wh and the device has three cells, the (total capacity=3*3.5)

What is the formula?

Note that if you have ampere-hours instead of mAh, you will have to divide the ampere-hour by 1000.

The energy in Watts-hour (Wh) equals milliamps-hour (mAh) times the voltage (V) divide by 1000.

E= Q*V, which represents Wh= mAh*v/1000

How to do the calculation

You can use the electric charge in milliamps-hour (mAh) to power into watts-hour (Wh) calculator.

When using this calculator, you need to incorporate the formula (Wh=mAh*v) Enter the milliamps-hour (mAh) and voltage in volts (v), and calculate.

For instance, you want to convert 5000 milliamps-hour (mAh) into watts-hour(Wh), and the battery’s voltage is 10V.

Multiply 5000 milliamps-hour (mAh)* 10V voltage, then divide this sum by 1000. The answer to this equation=50 watts-hour (Wh)

Tips on calculation

You need to familiarize yourself with various physics concepts and calculations of various standard units of measurements such as amperes (A), Voltage (V), etc.

Note that 1 Ampere-hour (Ah) equals 1000 milliampere-hours (mAh). Also note that battery capacity, power output, and rated capacity are different concepts.

Understand these concepts well to avoid confusion when comparing battery capacity in watts-hour (Wh) of various batteries.

To sum up, the milliampere-hour (mAh) to watts-hour (Wh) calculator typically uses the formula Wh= mAh*V.

Having the voltage and milliampere-hour of a battery, you can calculate the Watts-hour. Also, understand various units and formulas for measurement of power.
