Metric Horsepower (CV) to dBm Converter
Power · unit-converter
Convert Metric Horsepower (CV) to dBm 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 (CV)
CV (cheval-vapeur) is a metric horsepower unit equivalent to 735.49875 W, commonly used in European market specs.
About dBm
dBm is a logarithmic power level relative to 1 mW: P(W) = 10^((dBm − 30)/10). It is standard in RF and telecommunications; it is not a linear multiple of the watt.
How to convert metric horsepower (cv) to decibels relative to 1 mw (dbm)
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 (CV), multiply by 735.49875 W per cv to get watts, then apply the dBm formula (watts must be positive).
Examples
Example #1: Convert 10 cv to dbm
10 cv → 68.665819 dbm
Example #2: Convert 30 cv to dbm
30 cv → 73.437032 dbm
Summary
To convert Metric Horsepower (CV) to dBm, multiply by watts per cv, then apply dBm: dBm = 10 × log₁₀(P_W × 1000), where P_W = value_cv × 735.49875. Watts must be positive.
Relationship context
You are converting between mechanical power (horsepower, ft·lb/s) (Metric Horsepower (CV)) and logarithmic RF levels (dBm) (Decibels relative to 1 mW (dBm)). 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.
