Convert Nanowatts to Milliwatts
Convert Nanowatts (nW) to Milliwatts (mW) instantly and accurately.
Conversion Formula
mW = nW × 1.000000000e-6
About Nanowatts
A nanowatt (nW) is 10⁻⁹ W - the power scale of ultra-low-power embedded systems. Cardiac pacemakers deliver sensing pulses at nanowatt levels to preserve 7-10 year battery life. RFID tags harvest ~10-200 nW from reader fields. Solar cells in wristwatches and calculators operate on ambient indoor light yielding tens of nanowatts. A standard AA cell (13,500 J) discharged at 1 nW would last over 400 years. Neuromorphic chips target 10-100 nW per neuron-equivalent circuit. 1 nW = 10⁻⁹ W.
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.
