Formula

watts = value x unit factor (1 hp = 550 ft-lbf/s = 745.6998715822702 W; 1 PS = 75 kgf-m/s = 735.49875 W)

Understanding Power Conversion

Power is the rate of doing work, with the watt (one joule per second) as the SI unit. Engines are still rated in horsepower in many markets. Mechanical horsepower (used in the US and UK) is exactly 550 foot-pounds per second, about 745.7 W, while metric horsepower (PS or CV, used in continental Europe) is 75 kilogram-force meters per second, about 735.5 W. Air conditioners and furnaces are often rated in BTU per hour.

Tips and Best Practices

  • 1Multiply horsepower by 0.7457 to get kilowatts.
  • 2Multiply kilowatts by 1.341 to get mechanical horsepower.
  • 3One BTU per hour is about 0.293 W.

Real-World Example

A 150 hp engine delivers 150 x 745.7 = 111.85 kW. A 12,000 BTU/h air conditioner draws about 12,000 x 0.29307 = 3,517 W of cooling capacity.

Common Mistakes to Avoid

  • Treating metric and mechanical horsepower as the same; they differ by about 1.4 percent.
  • Confusing BTU (energy) with BTU per hour (power).
  • Reading a kW rating as kWh.

How to Use

  1. Type a number in the Kilowatts box.
  2. The Horsepower (metric) result appears instantly; you can also edit the Horsepower (metric) box to convert backwards.
  3. Use the swap button to reverse the direction and Copy result to copy the answer.

Frequently Asked Questions

Q

How many horsepower (metric) are in 1 kW?

1 kW equals 1.3596216 PS.
Q

How many kilowatts are in 1 PS?

1 PS equals 0.73549875 kW.
Q

What is the formula to convert kilowatts to horsepower (metric)?

watts = value x unit factor (1 hp = 550 ft-lbf/s = 745.6998715822702 W; 1 PS = 75 kgf-m/s = 735.49875 W).
Q

Is a PS the same as a hp?

No. One metric horsepower (PS) is 735.49875 W, slightly less than a mechanical horsepower.

Sources: NIST SP 811 (horsepower = 550 ft lbf/s; BTU_IT); DIN 66036 (metric horsepower = 75 kgf m/s with g_n = 9.80665 m/s2).
