Convert Milliwatts to Microwatts
Convert Milliwatts (mW) to Microwatts (µW) instantly and accurately.
Conversion Formula
µW = mW × 1000
About Milliwatts
A milliwatt (mW) is 10⁻³ W - the power scale of consumer wireless communications. Wi-Fi access points transmit at 100 mW (20 dBm); mobile phones peak at up to 1,000 mW. A laser pointer emits 1-5 mW; an LED indicator 10 mW; Bluetooth Classic peaks at 100 mW. Standby power implications: 1 mW × 10⁹ devices × 1 year = 8,760 MWh - enough to power a small town, underscoring why milliwatt standby matters at scale. 1 mW = 10⁻³ W.
About Microwatts
A microwatt (µW) is 10⁻⁶ W - the operational power band for autonomous IoT sensors and energy-harvesting wearables. Quartz oscillators in microcontrollers consume 1-10 µW; thermoelectric wearables harvesting body heat produce 10-100 µW. NFC tags derive ~10-200 µW from the reader field. Cochlear implants and implantable glucose sensors operate at microwatt levels to minimise tissue heating. 1 µW = 10⁻⁶ W.
