Metric Horsepower (PS/CV) to Horsepower (mechanical) Converter
Power · unit-converter
Convert Metric Horsepower (PS/CV) to Horsepower (mechanical) with a fixed input and output unit, step-by-step formula line, and reference tables. Linear units use SI watt definitions; mechanical hp uses 550 ft·lbf/s; BTU/h uses the IT BTU; dBm/dBW are logarithmic relative to 1 mW and 1 W. The full Power Converter also includes PS/CV, TR, kVA/MVA, and ft·lb/s.

About Metric Horsepower (PS/CV)
PS is metric horsepower (also called Pferdestarke), defined as 735.49875 W. It appears widely in EU and Korean vehicle specs.
About Horsepower (mechanical)
Mechanical horsepower here is the US definition: 550 ft·lbf/s ≈ 745.70 W. Automotive and industrial specs often cite hp.
How to convert metric horsepower (ps/cv) to horsepower (mechanical, 550 ft·lb/s)
1 metric horsepower (ps/cv) is equal to 0.98632007061953 horsepower (mechanical) when both are expressed in watt-equivalents:
1 ps = (735.49875 W ÷ 745.6998715822702 W) hp = 0.98632007061953 hp
Each metric horsepower (ps/cv) is defined as 735.49875 W and each horsepower (mechanical) as 745.6998715822702 W in this tool, so one ps equals 735.49875 ÷ 745.6998715822702 hp = 0.98632007061953 hp.
Let d(ps) be the numeric value in Metric Horsepower (PS/CV) (ps), and d(hp) the value in Horsepower (mechanical) (hp). Then:
d(hp) = d(ps) × (735.49875 / 745.6998715822702)
Equivalently, divide by how many ps fit into one hp (watts per hp divided by watts per ps):
d(hp) = d(ps) ÷ 1.013869665424
Or: horsepower (mechanical) = metric horsepower (ps/cv) ÷ 1.013869665424
Examples
Example #1: Convert 1 ps to horsepower (mechanical)
1 ps = 1 ps × (735.49875/745.6998715822702) hp = 0.9863200706 hp
1 ps = 1 ps ÷ 1.013869665424 = 0.9863200706 hp
Intermediate watts: 735.49875 W
Example #2: Convert 10 ps to horsepower (mechanical)
10 ps = 10 ps × (735.49875/745.6998715822702) hp = 9.8632007062 hp
10 ps = 10 ps ÷ 1.013869665424 = 9.8632007062 hp
Intermediate watts: 7,354.9875 W
Summary
To convert Metric Horsepower (PS/CV) to Horsepower (mechanical), multiply the value in ps by the ratio of watts per ps divided by watts per hp. Equivalently: value_hp = value_ps × (735.49875 / 745.6998715822702). Numerically, 1 ps equals 0.986320070619531 hp.
Relationship context
Both units are mechanical power (horsepower, ft·lb/s). Conversions use fixed watt factors, so results stay consistent with the definitions in this converter. The factor from Metric Horsepower (PS/CV) to Horsepower (mechanical) is 9.863201e-1 (1 ps = 0.986320070619531 hp).
