About Converting Centiwatts to Metric horsepowers
Centiwatt and Metric horsepower both describe power output, and the conversion is a routine part of comparing an engine or motor's spec sheet across countries that use different power units. Specifically: Centiwatt is 0.01 watt units, and metric horsepower.
Formula
metric horsepowers = centiwatts × 0.000013596216173
This factor comes from each unit's defined relationship to the category's base unit: 1 centiwatt equals 0.01 base units, and 1 metric horsepower equals 735.49875 base units, so dividing one by the other gives the direct centiwatt-to-metric horsepower factor of 0.000013596216173.
Simple example
1 cW × 0.00001359621617 = 0.0000135962 PS
1 centiwatt = 0.0000135962 metric horsepowers.
Real-world example
100 cW × 0.00001359621617 = 0.0013596216 PS
100 centiwatts = 0.0013596216 metric horsepowers.

Reverse conversion: Metric horsepower to Centiwatt
0.0000135962 PS × 73549.875 = 0.9999988105 cW
0.0000135962 metric horsepowers = 0.9999988105 centiwatts.
centiwatts = metric horsepowers × 73549.875

Understanding the Centiwatt (cW)
Centiwatt is 0.01 watt units.
Understanding the Metric horsepower
Metric horsepower (PS) measures power. Metric horsepower (PS/CV) is defined as exactly 735.49875 watts, the power to raise 75 kilograms one meter per second. It is classified as a Non-SI unit (metric, automotive).
Where it's used: Continental Europe, Japan, and other metric-system automotive markets
Uses of the Metric horsepower today
- European and Japanese vehicle engine power ratings (often shown as PS or CV)
- Motor and machinery power specifications in metric countries
History of the Metric horsepower
Metric horsepower emerged in continental Europe in the 19th century as engineers sought a metric-system analog to Watt's English horsepower, defining it via a round figure (75 kgf·m/s) convenient in metric calculations. It remains the standard automotive power unit across much of Europe and Asia, labeled PS (German 'Pferdestärke') or CV (French/Italian 'cheval-vapeur').
Historical origin. Metric horsepower was not the invention of a single named person; it developed through the process described above.
