How to convert Wh to mAh?

Description of electricity or battery capacity, the most commonly used units of measurement include watt-hour, kilowatt hour, milliampere hour, volt, etc., to understand the relationship between these units, the use of the formula can be simple to convert different unit values, such as convert Wh to mAh.

What is Watt-hours?

Watt-hours (Wh) are a unit of energy measurement. It represents the amount of energy consumed or produced over a period of one hour 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 (in watts) by the time (in hours) during which the power is consumed or produced.

What is Milliamp-hour?

Milliamp-hour (mAh) is a unit of electric charge often used to measure the capacity of a battery. It represents one-thousandth of an ampere-hour (Ah). The milliamp-hour is commonly used to express the capacity of small batteries, especially in consumer electronics such as smartphones, tablets, and other portable devices.

The Portable Power Station on the market is usually measured in watt-hours, if you want to know the battery capacity milliampere-hours, the calculation method: battery capacity Q (mAh) is equal to the electrical energy E (Wh) divided by the voltage V (v), multiplied by 1000.

Formula: Watt-Hour ÷ Volts × 1000 = Milliamp-Hour

Abbreviated Formula: Wh ÷ V × 1000 = mAh

Example, if you have a 10Wh battery rated at 3.7V, the power is 10Wh * 1000 / 3.7V = 2702.7 mAh.
