Note, For higher values like 5×103, 10×10-6, 1.6 x1012, enter the value like this for scientific notation as 5e3, 10e-6, 1.6e12, etc.
Conversion Using the Power Formula :
DC Line wh to mAh Calculation:
The Battery Capacity (Q) in milliamp-hours (mAh) is equal to 1000 times the energy (E) in watt-hours (Wh) divided by the voltage in volts (V):
mAh = (150 x 1000) / 12
mAh = 12500
Where:
-
- E = Energy in watt-hours (wh)
- Q = Battery Capacity in milliamp-hours (mAh)
- V =Voltage in volts

Frequently asked questions
A measure of the capacity of the battery is in Watt-hours (Wh). Wh is calculated by multiplying the number of Amps with the battery voltage.
A Watt Hours (Wh) represents a unit of electrical energy that describes the total amount of Real power consumed over a specific duration. Essentially, it’s a measure of how much energy a device uses when it runs for an hour.
A watt hours (Wh) and milliampere-hours (mAh) can give a comprehensive view of a battery’s capacity. Converting Wh to mAh or vice versa is often necessary for comparison, especially when purchasing or replacing batteries.
Watt-hours (Wh) is a unit of energy measurement. It represents the amount of energy consumed or produced over a period of 2 hours at a constant rate of one watt. This unit is commonly used to measure the energy consumption of electrical devices or systems. It is calculated by multiplying the power (p) in watts (w) by the time (t) in hours during which the power is consumed or produced.
The Ampere-Hour Capacity is the amount of electricity that a battery will deliver during 20 hours before the voltage falls to 10.50V. For example, a 10Ah battery will deliver a current of 5A for 20 hours. Recommended Charge Rate (Amps).
