Convert Megawatts to Nanowatts
Convert Megawatts (MW) to Nanowatts (nW) instantly and accurately.
Conversion Formula
nW = MW × 1000000000000000
About Megawatts
A megawatt (MW) is 10⁶ W - the standard unit for utility power plant output. A coal unit produces 300-900 MW; a large nuclear reactor 1,000-1,600 MW. Offshore wind turbines reach 15 MW each (Vestas V236-15.0). The Three Gorges Dam totals 22,500 MW. Aluminium smelters consume 500-600 MW; electric arc furnaces 100-300 MW. Solar farms are rated in MWp; pharmaceutical clean-room HVAC systems in MW. 1 MW = 10⁶ W = 1,341 mechanical hp.
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.
