Convert Amp Hours to mAh: A Comprehensive Guide

Introduction

Understanding the relationship between amp hours (Ah) and milliamp hours (mAh) is crucial in various electrical applications, especially in designing and selecting batteries. This article provides a detailed guide on how to convert amp hours to mAh, highlighting its importance, benefits, and potential applications.

Understanding Amp Hours and Milliamp Hours

Amp Hours (Ah)

Amp hours represent the amount of electrical current that a battery or other energy source can deliver over a specified period of time. One amp hour is equivalent to the flow of one ampere of current for one hour.

Milliamp Hours (mAh)

Milliamp hours are an equivalent unit of electrical charge, but on a smaller scale. One milliamp hour is equal to one-thousandth of an amp hour, or 0.001 Ah.

Conversion Formula: Amp Hours to Milliamp Hours

To convert amp hours to milliamp hours, simply multiply the amp hour value by 1000.

mAh = Ah × 1000

How to Convert Amp Hours to mAh

Step 1: Determine Amp Hour Value

Obtain the amp hour rating of the battery or energy source you want to convert.

Step 2: Multiply by 1000

Multiply the amp hour value by 1000 to obtain the milliamp hour value.

Example:

Convert a battery with a rating of 5 Ah to mAh:

mAh = 5 Ah × 1000 = 5000 mAh
