Horsepower (mechanical) to Metric Horsepower (PS/CV) Converter
Power · unit-converter
Convert Horsepower (mechanical) to Metric Horsepower (PS/CV) 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 Horsepower (mechanical)
Mechanical horsepower here is the US definition: 550 ft·lbf/s ≈ 745.70 W. Automotive and industrial specs often cite hp.
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.
How to convert horsepower (mechanical, 550 ft·lb/s) to metric horsepower (ps/cv)
1 horsepower (mechanical) is equal to 1.013869665424 metric horsepower (ps/cv) when both are expressed in watt-equivalents:
1 hp = (745.6998715822702 W ÷ 735.49875 W) ps = 1.013869665424 ps
Each horsepower (mechanical) is defined as 745.6998715822702 W and each metric horsepower (ps/cv) as 735.49875 W in this tool, so one hp equals 745.6998715822702 ÷ 735.49875 ps = 1.013869665424 ps.
Let d(hp) be the numeric value in Horsepower (mechanical) (hp), and d(ps) the value in Metric Horsepower (PS/CV) (ps). Then:
d(ps) = d(hp) × (745.6998715822702 / 735.49875)
Equivalently, divide by how many hp fit into one ps (watts per ps divided by watts per hp):
d(ps) = d(hp) ÷ 0.98632007061953
Or: metric horsepower (ps/cv) = horsepower (mechanical) ÷ 0.98632007061953
Examples
Example #1: Convert 1 hp to metric horsepower (ps/cv)
1 hp = 1 hp × (745.6998715822702/735.49875) ps = 1.0138696654 ps
1 hp = 1 hp ÷ 0.98632007061953 = 1.0138696654 ps
Intermediate watts: 745.699871582 W
Example #2: Convert 10 hp to metric horsepower (ps/cv)
10 hp = 10 hp × (745.6998715822702/735.49875) ps = 10.1386966542 ps
10 hp = 10 hp ÷ 0.98632007061953 = 10.1386966542 ps
Intermediate watts: 7,456.99871582 W
Summary
To convert Horsepower (mechanical) to Metric Horsepower (PS/CV), multiply the value in hp by the ratio of watts per hp divided by watts per ps. Equivalently: value_ps = value_hp × (745.6998715822702 / 735.49875). Numerically, 1 hp equals 1.013869665424 ps.
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 Horsepower (mechanical) to Metric Horsepower (PS/CV) is 1.013870e+0 (1 hp = 1.013869665424 ps).
