Convert Nanowatts to Metric Horsepower
Convert Nanowatts (nW) to Metric Horsepower (PS) instantly and accurately.
Conversion Formula
PS = nW × 1.359621617e-12
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 Metric Horsepower
The metric horsepower (PS/CV/pk) equals exactly 75 kgf·m/s = 735.49875 W - the European equivalent of mechanical horsepower, defined as lifting 75 kg by 1 m/s. It was the DIN 66036 standard for European automotive ratings until the EU mandated kW. A 100 PS car produces 73.55 kW; 200 PS = 147.1 kW. The ~1.4% difference from mechanical hp (745.7 W) means a 100 PS car rates as 98.6 mechanical hp. German car advertising still shows PS parenthetically alongside kW. 1 PS = 735.49875 W.
