How to Convert Microamperes to Milliamperes: A Detailed Guide

Introduction

Microamperes (µA) and milliamperes (mA) are units of electrical current that are commonly used in electrical and electronic applications. Understanding the relationship between these units is essential for accurate measurements and calculations. This article provides a comprehensive guide on converting microamperes to milliamperes, covering the basics, conversion formulas, practical examples, and potential applications.

Conversion Formula

The conversion formula between microamperes and milliamperes is:

1 milliampere (mA) = 1000 microamperes (µA)

Or

1 microampere (µA) = 0.001 milliamperes (mA)

Conversion Table

The following table provides a conversion table for microamperes and milliamperes:

Practical Examples

Example 1: Convert 50 microamperes to milliamperes.

Solution:

50 µA * 0.001 mA/µA = 0.05 mA

Example 2: Convert 1.5 milliamperes to microamperes.

Solution:

1.5 mA * 1000 µA/mA = 1500 µA
