Convert Nanowatts to Petawatts
Convert Nanowatts (nW) to Petawatts (PW) instantly and accurately.
Conversion Formula
PW = nW × 1.000000000e-24
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 Petawatts
A petawatt (PW) is 10¹⁵ W. Total solar power intercepted by Earth is ~174 PW. The world's most powerful laser pulses operate at petawatt peak power via chirped pulse amplification (CPA, 2018 Nobel Prize in Physics): China's SULF demonstrated 10 PW in 2019; ELI-NP targets 10 PW. These PW pulses last femtoseconds and create plasma temperatures of billions of kelvin in laboratory targets. Gamma-ray bursts radiate 10²⁴-10²⁷ W at peak - thousands to billions of times the petawatt scale. 1 PW = 10¹⁵ W.
