Step-by-Step Engineering Calculation

  1. 1Conversion factor: 1 Mechanical HP=745.70 W1\text{ Mechanical HP} = 745.70\text{ W}
  2. 2Watts Conversion: 7.5 kW×1000=7500 W7.5\text{ kW} \times 1000 = 7500\text{ W}
  3. 3Calculated HP: 7500 W745.70 W/HP=10.0577 HP\frac{7500\text{ W}}{745.70\text{ W/HP}} = \mathbf{10.0577\text{ HP}}

Conversion Formula & Relationship

HP_mech = kW × 1000 / 745.699872 | HP_metric = kW × 1000 / 735.49875

Converts electrical kilowatt rating into mechanical output shaft horsepower.

Standard Conversion Example

Input: 7.5 kW Electric Motor
Result: 10.06 Mechanical HP (10.20 Metric HP)

7.5 kW × 1000 / 745.7 = 10.058 HP.

7.5 kW Electric Motor = 10.06 Mechanical HP (10.20 Metric HP)
