How to convert kilowatts to mechanical horsepower
Mechanical horsepower is 550 foot-pounds-force per second. Metric horsepower uses 75 kilogram-force meters per second and has a different value.
Use x for the value in kW, b for the intermediate value in W, and y for the result in hp.
hp = kW × 1000 ÷ 745.6998715822702
Worked examples
10 kW ≈ 13.410220896 hp
Step 1: (10 × 1000) ≈ 10000 W.
Step 2: 10000 ÷ 745.699871582 ≈ 13.410220896 hp.20 kW ≈ 26.8204417919 hp
Step 1: (20 × 1000) ≈ 20000 W.
Step 2: 20000 ÷ 745.699871582 ≈ 26.8204417919 hp.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Kilowatts
Kilowatts (kW) measures power under the conventions above. The base value in W is (x × 1000), where x is the numerical value in kW. Factors shown here are rounded for display; calculations use the stored factor.
