Horsepower Formula:
From: | To: |
Definition: This calculator converts motor power from kilowatts (kW) to horsepower (HP).
Purpose: It helps engineers, mechanics, and technicians compare motor power ratings between metric (kW) and imperial (HP) systems.
The calculator uses the formula:
Where:
Explanation: 1 kilowatt equals approximately 1.341 horsepower. This conversion factor is based on the mechanical definition of horsepower.
Details: Many motor specifications use different units in different regions. Accurate conversion ensures proper motor selection and performance comparison.
Tips: Simply enter the motor power in kilowatts (kW). The value must be > 0.
Q1: What's the exact conversion factor?
A: 1 kW = 1.34102209 HP, but 1.341 is sufficiently precise for most applications.
Q2: Is this for mechanical or electrical HP?
A: This uses mechanical horsepower (745.7 W). Electrical horsepower is slightly different (746 W).
Q3: Can I convert HP back to kW?
A: Yes, divide HP by 1.341 or multiply by 0.7457.
Q4: Why do some motors show both kW and HP?
A: Many manufacturers list both to accommodate international markets with different standard units.
Q5: Does this apply to all types of motors?
A: Yes, the conversion is the same for electric, hydraulic, and combustion motors - it's a unit conversion, not motor-specific.
