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 Boiler Horsepower

One boiler horsepower (BHP) ≈ 9,810 W = 33,475 BTU/h - the power to evaporate 34.5 lb of water per hour at 212°F, standardised by ASME for rating steam boilers. A small office building needs 10-50 BHP; a hospital or large plant 200-2,000 BHP. Critically, 1 BHP is ~13.1× larger than 1 mechanical horsepower (746 W) - a dangerous confusion when specifying heating equipment. 1 BHP ≈ 9,810.6 W.
