A horsepower-hour (hph) is an outdated unit of energy, not used in the SI system of units. The unit represents an amount of work a horse is supposed capable of delivering during an hour (1 (one) horsepower integrated over a time interval of an hour). Based on differences in the definition of what constitutes the 'power of a horse', a horsepower-hour differs slightly from the German "Pferdestärkenstunde" (PSh):
| 1 horsepower-hours = 0.025450411049787 therms | 6 horsepower-hours = 0.15270246629872 therms |
| 2 horsepower-hours = 0.050900822099575 therms | 7 horsepower-hours = 0.17815287734851 therms |
| 3 horsepower-hours = 0.076351233149362 therms | 8 horsepower-hours = 0.2036032883983 therms |
| 4 horsepower-hours = 0.10180164419915 therms | 9 horsepower-hours = 0.22905369944809 therms |
| 5 horsepower-hours = 0.12725205524894 therms | 10 horsepower-hours = 0.25450411049787 therms |
The therm (symbol thm) is a non-SI unit of heat energy equal to 100,000 British thermal units (BTU). It is approximately the energy equivalent of burning 100 cubic feet (2.83 cubic metres) – often referred to as 1 CCF – of natural gas.
