Convert Milliwatts to Picowatts

Convert Milliwatts (mW) to Picowatts (pW) instantly and accurately.

Conversion Formula

pW = mW × 1000000000

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 Picowatts

A picowatt (pW) is 10⁻¹² W - the power scale of the most sensitive radio receivers. GPS satellites transmit 20-50 W; by the time that signal spans 20,000 km, the received power is ~0.1 pW (−130 dBm). Radio telescopes routinely detect cosmic signals in the picowatt range. Qubit control electronics in quantum computers must resolve energy differences at picowatt scales. Photodetectors in single-photon counting mode, hard drive head read-back signals at idle, and deep-shadow solar cells also operate at picowatt levels. 1 pW = 10⁻¹² W.
