You need to know the voltage as well before the conversion can be made.
You are thinking watts to horsepower, not amps to horsepower. Please restate the question.
Amps.
A single-phase induction motor uses variable amounts of current depending on the load etc. but on a 240 v system you should allow 7 amps per horsepower, so 35 amps for 5 HP.
1 HP = 746 watts. Watts = amps x volts. 7 x 110 = 770 watts. 770/746 = 1.032 HP
Volts don't make power. Watts do. Watts = (volts) x (amps) 1 horsepower = 746 watts
That answer depends on many different factors. Could be anything from 5 to 35 hp.
To calculate horsepower, you can use the formula: Horsepower = (Volts x Amps x Efficiency) / 746. Using 110 volts and 15 amps, and assuming 90% efficiency, the formula would be: (110 x 15 x 0.9) / 746 = 1.49 horsepower.
35
Depends on the voltage. If you are running off 120 VAC, a 0.5 horsepower motor would draw 3.1 A.
How to convert horsepower to amps? You'd have to make an assumption about volts. If it's running at 220 volts, that would make it 34 Amps. There are 746 watts in a horsepower and Amps = Watts/Volts.
You don't. The units measure different things.
One horsepower (hp) is approximately equal to 746 amps (A) in direct current (DC) systems. However, converting between amps and horsepower may require additional information such as voltage, efficiency, and power factor in alternating current (AC) systems.
