James Watt didn't use a horse to find horse power
James Watt
If I did the conversion right it is 18.64 since one watt is equal to 0.001341 horse power.
You are probably confusing energy for power. A 'unit', which is short for 'Board of Trade Unit', is equivalent to a kilowatt hour, which is used to measure energy, notpower.
746 > 1 (imperial) horsepower ( 33 000 lbsf - feet / min ) = 745.699 watts
james watt is remembered for measuring the power of his steam engine: his test with a strong horse resulted in his determination that a "horsepower"was 550 foot-pounds per second. The unit of power in the metric system is called the watt; one horsepower equals 746 watts.
James Watt was a Scottish inventor and mechanical engineer. He improved the steam engine, developed the concept of horse power and invented the copying machine.
1 watt-hour equals 1 watt times 1 hour, or 3600 joules.
It will power two 400 watt lamps.
Displacement doesn't directly equivocate to horsepower.
800 watt should be fine
Watt was competing with horse power for business. He pitched his new steam engine in terms of the number of horses it could replace.
