- boiler horsepower
- a traditional unit measuring the power delivered by a boiler. The boiler horsepower is defined to be the power required to convert 30 pounds (13.61 kilograms) per hour of water at 100 °F (37.78 °C) to saturated steam at a pressure of 70 pounds per square inch gauge (482.6 kilopascals gauge). This power, about 33 471 Btu per hour or 9.8095 kilowatts, is more than 13 times the usual mechanical definition of the horsepower, but it is judged sufficient to run an engine producing one horsepower of mechanical power.
