About This Launch
A free, no-signup electrical power converter for students, technicians, and electronics hobbyists. Switch between milliwatts to watts and watts to milliwatts and see the exact equality. It explains the SI prefix relationship, distinguishes mW from MW, and includes a power-scale chart, examples, a conversion table, and CSV export.
