Convert Microwatts to Boiler Horsepower
Convert Microwatts (µW) to Boiler Horsepower (BHP) instantly and accurately.
Conversion Formula
BHP = µW × 1.019310421e-10
About Microwatts
A microwatt (µW) is 10⁻⁶ W - the operational power band for autonomous IoT sensors and energy-harvesting wearables. Quartz oscillators in microcontrollers consume 1-10 µW; thermoelectric wearables harvesting body heat produce 10-100 µW. NFC tags derive ~10-200 µW from the reader field. Cochlear implants and implantable glucose sensors operate at microwatt levels to minimise tissue heating. 1 µW = 10⁻⁶ 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.
