1. Introduction:
Power, the rate at which work is done or energy is transferred, stands as a fundamental concept in physics and engineering. The milliwatt (mW) unit represents a metric to quantify power, signifying a magnitude that lies between the realms of microwatt and watt. Milliwatt power finds extensive applications in various scientific domains, including electronics, telecommunications, optical systems, and energy consumption. This article aims to provide a comprehensive overview of the concept of milliwatt power, its measurement techniques, and its impact on scientific research and technological advancements.

2. Understanding Milliwatt (mW) Power:
The milliwatt (mW) is a derived unit of power in the International System of Units (SI). It represents one thousandth (1/1000) of a watt (W), where a watt denotes the power equivalent to one joule of energy transferred per second. Therefore, milliwatt power symbolizes a magnitude that is one thousandth of a watt, providing a suitable scale for measuring relatively small amounts of power. Milliwatt power is particularly relevant in applications where low power consumption, efficient energy utilization, and precise power measurements are essential.
