Milliampere-hour (mAh) in Electric Charge

What is Milliampere-hour (mAh)

Milliampere-hour, commonly abbreviated as mAh, is a unit of electric charge. It quantifies how much electricity a battery can deliver over a certain period of time. Specifically, it indicates the amount of current (in milliamperes) that can flow for one hour before the battery runs out of energy. The "milli-" prefix signifies one-thousandth, so 1 mAh refers to a current of 1 milliampere being used for 1 hour.

To understand mAh better, consider that a device draws a specific amount of current while operating. For instance, if a battery is rated at 1000 mAh, it can theoretically support a device using 100 mA for 10 hours, or a device using 500 mA for 2 hours. This makes mAh a useful measure for evaluating battery life in portable devices like smartphones, tablets, and electric vehicles.

The mAh rating helps consumers gauge the longevity of batteries, but it does not directly indicate how long a device will last on a specific battery without knowing the current draw of that device.

Common Conversion Values

The milliampere-hour can be converted into different units of electric charge. Below are some common conversion values:

• 1 (mAh)=3.6 (C)
• 1 (mAh)=3600 (mC)
• 1 (mAh)=3600000 (µC)
• 1 (mAh)=3600000000 (nC)
• 1 (mAh)=0.0036 (kC)
• 1 (mAh)=0.0000036 (MC)
• 1 (mAh)=0.36 (abC)
• 1 (mAh)=60 (mAmin)
• 1 (mAh)=3600 (mAs)
• 1 (mAh)=0.001 (Ah)
• 1 (mAh)=0.06 (Amin)
• 1 (mAh)=3.6 (As)
• 1 (mAh)=0.00003731137 (F)

These conversions can be useful in various scientific and engineering applications. Understanding these relationships allows for better evaluation and design of electronic devices and their power sources.
