Hp to Amps Calculator

by




Result: Amps

The HP to Amps calculator is a valuable tool for electrical engineers, technicians, and anyone working with electric motors. It allows you to quickly and accurately convert a motor’s power rating from horsepower (HP) to amperage (amps). This conversion is crucial when sizing electrical components and ensuring safe and efficient operation of motors.

Formula:

To convert from horsepower (HP) to amperage (amps), you can use the following formula:

Amps (A) = Horsepower (HP) × 746 / Voltage (V)

Where:

  • Amps (A) is the current in amperes.
  • Horsepower (HP) is the power rating of the motor.
  • Voltage (V) is the operating voltage of the motor (usually 120V for household applications).

Example:

Suppose you have a motor with a power rating of 2 HP and operates at 120V. To find the amperage, you can use the formula:

Amps (A) = 2 HP × 746 / 120V Amps (A) = 12.43 A

So, the motor draws approximately 12.43 amps of current.

How to Use:

  1. Enter the motor’s power rating in HP in the input field.
  2. Click the “Calculate” button.
  3. The calculator will display the amperage in the result field.
