Metric Horsepower (PS/CV) to dBW Converter
Power · unit-converter
Convert Metric Horsepower (PS/CV) to dBW 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 dBW
dBW is a logarithmic power level relative to 1 W: P(W) = 10^(dBW/10). RF, microwave, and antenna work often use dBW with dBm.
How to convert metric horsepower (ps/cv) to decibels relative to 1 w (dbw)
dBm/dBW are logarithmic power levels. P_W = 10^((dBm − 30) / 10), P_W = 10^(dBW / 10), and inverse mappings use 10 × log₁₀(·) with P_W > 0.
From Metric Horsepower (PS/CV), multiply by 735.49875 W per ps to get watts, then apply the dBm formula (watts must be positive).
Examples
Example #1: Convert 10 ps to dbw
10 ps → 38.665819 dbw
Example #2: Convert 30 ps to dbw
30 ps → 43.437032 dbw
Summary
To convert Metric Horsepower (PS/CV) to dBW, multiply by watts per ps, then apply dBW: dBW = 10 × log₁₀(P_W), where P_W = value_ps × 735.49875. Watts must be positive.
Relationship context
You are converting between mechanical power (horsepower, ft·lb/s) (Metric Horsepower (PS/CV)) and logarithmic RF levels (dBm) (Decibels relative to 1 W (dBW)). Log units (dBm/dBW) use base-10 definitions relative to 1 mW or 1 W; linear units map through watts first, then to or from the selected log unit. Only strictly positive power in watts maps to a real dB power value.
