How do I convert HP to amps?
Given horsepower and volts, it is possible to calculate amps. The calculation of amps uses Ohm’s Law, which is amps times volts equals watts. Multiply the horsepower by 746 watts. For example, an engine at two horsepower with 230 volts would be calculated as two horsepower times 746 watts, which equals 1492.
How strong is a 1 hp motor?
Horsepower, the common unit of power; i.e., the rate at which work is done. In the British Imperial System, one horsepower equals 33,000 foot-pounds of work per minute—that is, the power necessary to lift a total mass of 33,000 pounds one foot in one minute.

How is hp calculated?
The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252.
How many hp is RPM?
In other words, power is the rate of completing work (or applying torque) in a given amount of time. Mathematically, horsepower equals torque multiplied by rpm. H = T x rpm/5252, where H is horsepower, T is pound-feet, rpm is how fast the engine is spinning, and 5252 is a constant that makes the units jibe.
How much hp can lift?
One mechanical horsepower lifts 550 pounds (250 kg) by 1 foot high in 1 second. Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower.
