The Uses of Horsepower (Metric) units to Watts Conversion
Metric horsepower is the traditional unit for rating European engines and machinery, so this conversion is most useful when comparing against an electric motor or electrical supply figure given in watts.
Comparing European Car Specs to Electric Motor Ratings
Automotive engineers who know an electric motor's rated output in watts convert a European car's metric horsepower rating into watts to compare the two power sources directly.
Sizing Metric-Rated Industrial Machinery
Mechanical engineers working with European industrial machinery rated in metric horsepower convert the figure into watts to cross-check against the electrical supply capacity available on site.
Checking Imported Equipment Documentation
Technicians servicing imported European equipment labeled in metric horsepower convert the rating into watts to compare against domestic electrical specifications.

Frequently Asked Questions
How many watts are in 1 horsepower (metric)?
1 horsepower (metric) equals 735.499 watts, a figure useful for anyone working at the European automotive and metric engineering power ratings scale.
How many horsepower (metric) units are in 1 watt?
1 watt equals approximately 0.00135962 horsepower (metric)s, which puts the size of a single watt into perspective against the horsepower (metric).
Why would anyone convert metric horsepower to watts?
This comes up whenever a European engine or metric-rated machine specified in metric horsepower needs to be compared against an electric motor or electrical supply figure in watts.
How is metric horsepower different from standard mechanical horsepower?
Metric horsepower (735.5 watts) is slightly smaller than the imperial mechanical horsepower (745.7 watts), since it's defined as 75 kilogram-force meters per second rather than 550 foot-pounds per second.
