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. Two common definitions being used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 …
Electric motor horsepower: this article explains how to calculate the horsepower of an electric motor if we know its wattage or current draw in amps. The article gives a simple formulat to convert electrical amps to horsepower and explains what data are actually needed to make an accurate horsepower calculation or rating. We explain the relationship between running load amps (RLA), and full ...

· Though horsepower units are a derivative of the 33,000 ft-lbf/min, it is not critical to understanding how to calculate motor horsepower for speed and torque. Another common unit of power that motors are rated in is watts. The conversion from watts to horsepower is 745.7 watts = 1 hp.
Engine Horsepower Calculator. The following two calculators can be used to estimate the engine horsepower of a vehicle based on the weight of the vehicle, elapsed time, and speed used to finish a quarter mile run. Vehicle weight should include not only the vehicle, but also the driver, the passenger, and anything else of significant weight.
For a 1-phase supply with power rating in horsepower (hp): Note that the motor rated full load current is specified on the motor datasheet and stamped on the motor nameplate. However, this calculator is useful when only the motor rating is available and an estimate of the current is required.
Free Horsepower Calculator. Engine Rear Wheel Horsepower Calculator Based on total vehicle weight and 1/4 mile MPH. To use this horsepower calculator enter the mph trap speed at the 1/4 mile mark from one of your dragstrip ET slips. Then enter the total weight of your vehicle, as raced, including the drivers weight.

The first step to convert HP to amps is convert HP to watts. Since 1 HP is equal to 746 W simply multiply the horsepower by 746 for this conversion. Watts = Horsepower × 746. Account for Efficiency. Since motors are not 100% efficient, the number of amps needed to achieve the power output is actually higher depending on the efficiency.
To find the electric horsepower of a motor, use the equation: Horsepower = (Volts x Amps) / 745.7 (does not take efficiency into consideration) Example: The electric horsepower of a motor with 120 volts and 10 amps is: HP = (120 x 10) / 745.7. Calculated out this gives an electric horsepower of 1.6092.

Because 1 horsepower is equal to 746 watts, the formula above will include a division by 746 to complete the conversion. One additional consideration that should be made when doing the conversion is the efficiency of the motor being used.
P (hp) = 10kW / 0.745699872 = 13.41 hp . Kilowatts to electrical horsepower. One electrical horsepower is equal to 0.746 kilowatts: 1 hp(E) = 746 W = 0.746 kW. So the power conversion of kilowatts to horsepower is given by: P (hp) = P (kW) / 0.746. Example. Convert 10kW to electrical horsepower: P (hp) = 10kW / 0.746 = 13.405 hp . Kilowatts to ...
