Convert Boiler Horsepower to Gigawatts
Convert Boiler Horsepower (BHP) to Gigawatts (GW) instantly and accurately.
Conversion Formula
GW = BHP × 9.810554074e-6
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.
About Gigawatts
A gigawatt (GW) is 10⁹ W - the scale of national grid capacity. UK peak demand is 40-70 GW; France 80-100 GW. Japan's Kashiwazaki-Kariwa nuclear complex totals 8.2 GW. World installed solar PV surpassed 1,000 GW in 2022. The North Sea Link Norway-UK undersea cable carries 1.4 GW. Global data centre consumption exceeds 200 GW. A lightning bolt peaks at ~1 GW for ~30 µs, yielding only ~250 kJ total energy - power is extreme, energy modest. 1 GW = 10⁹ W.
