About converting Foot-pounds/min to Horsepower
Foot-pounds/min (ft·lb/min) and Horsepower (hp) are both units of power, so converting between them is a single multiplication: multiply your Foot-pounds/min figure by 0.0000303. Ten Foot-pounds/min comes to 0.000303 Horsepower, and a hundred works out at 0.00303 Horsepower.
Rule of thumb: going from Foot-pounds/min to Horsepower divides, so the figure always shrinks — it takes about 33,000 Foot-pounds/min to make a single Horsepower. If your answer came out bigger, you have the conversion the wrong way round.
What is a Foot-pound per Minute?
The foot-pound per minute is the raw ingredient horsepower was built from. It is exactly what it says: the work of lifting a pound through a foot, done once a minute. James Watt’s original estimates of what a horse could do were made in these terms, and mechanical horsepower is still formally defined as 33,000 of them — which is why horsepower converts to such an untidy number of watts. On its own the unit is now mostly a teaching device and a fixture of older American engineering texts, appearing where someone wants to show the arithmetic behind a horsepower rating rather than simply quote it.
What is a Horsepower?
Horsepower is a marketing unit that became a standard. James Watt devised it to sell steam engines to mine owners who had never bought an engine but had bought plenty of horses: by measuring what a draught horse could actually lift over a working day, he could quote an engine as worth so many horses and let the buyer do the arithmetic. Mechanical or imperial horsepower is defined as exactly 550 foot-pounds-force per second, which is why it lands on no tidy figure in watts. Two and a half centuries after the horses left, it is still how cars, outboards and lawn tractors are advertised.
To put both in perspective: someone climbing stairs steadily works at a few thousand foot-pounds per minute, while a family hatchback makes something like 120 horsepower.
