Convert Boiler Horsepower to Terawatts
Convert Boiler Horsepower (BHP) to Terawatts (TW) instantly and accurately.
Conversion Formula
TW = BHP × 9.810554074e-9
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 Terawatts
A terawatt (TW) is 10¹² W. All of human civilisation consumes ~17-18 TW (electricity + heat + transport combined); global electricity generation alone is ~9 TW. Solar irradiance intercepted by Earth is ~174,000 TW; photosynthesis captures ~130 TW. The National Ignition Facility (NIF) fusion laser produces pulses of ~500 TW lasting nanoseconds. High-power laser facilities for nuclear physics and ICF research routinely exceed 1 TW in ultrashort pulse regimes. 1 TW = 10¹² W.
