Convert hp to kw

Horsepower (mechanical)

Mechanical horsepower is a power unit equal to 745.6998715823 watts.

Horsepower originated as a practical way to compare engine output with animal work rates and remains common in mechanical ratings.

hp is used for engines, electric motors, pumps, compressors, fans, vehicles, and machinery specifications.

Kilowatt

A kilowatt is an SI power unit equal to 1000 watts.

Kilowatts became a practical scale for machinery, electrical systems, appliances, and medium-sized power ratings.

kW is used for motors, generators, appliances, EV chargers, HVAC equipment, solar arrays, and electrical load planning.

How to Convert Horsepower (mechanical) to Kilowatt

Mathematically, kilowatt (kW) = horsepower (mechanical) (hp) converted with the formula below.

1 hp = 0.7457 kW

1 kW = 1.341022 hp

Formula: value × 0.745699871582

Example: 15 hp = 11.185498 kW

1. Start with the power value in mechanical horsepower.
2. Use 1 hp = 745.6998715823 W.
3. Convert watts to kilowatts by dividing by 1000.
4. Multiply horsepower by 0.7456998715823 to get kilowatts.

Precision note: This converter uses mechanical horsepower: 1 hp = 0.7456998715823 kW. Metric horsepower and other definitions differ slightly.
