This tool converts horsepower to kilowatts quickly and accurately for your convenience.
How to use the HP to KW Calculator
To use the HP to KW calculator, simply enter the horsepower (HP) value and the efficiency percentage of the motor. After entering these values, click the “Calculate” button. The results table will display the power in kilowatts (KW) and the effective power considering the efficiency percentage.
Explanation of Calculation
Horsepower (HP) is a unit of power, and it can be converted to kilowatts (KW) using the following relationship: 1 HP = 0.7457 KW. To calculate the kilowatt value:
- Convert HP to KW by multiplying the HP value by 0.7457.
- Adjust for efficiency by multiplying the KW value by the efficiency percentage divided by 100.
Limitations
This calculator assumes that the efficiency percentage is entered correctly and that the motor operates within the specified efficiency range. The calculations are straightforward but may not account for specific operational conditions or losses that occur in real-world scenarios.
