Converting watts to milliwatts is a straightforward process essential in various scientific and engineering applications. Since one watt equals 1,000 milliwatts, you can determine the equivalent milliwatts by multiplying the number of watts by 1,000. For example, to convert 5 watts to milliwatts: 5 W × 1,000 = 5,000 mW. This conversion is crucial when dealing with low-power devices, such as laser pointers or hearing aids, which typically operate in the milliwatt range. Understanding this relationship aids in accurate power measurements and ensures compatibility across different systems and devices.
