Formula
Millijoule (mJ) measures energy, while Metric horsepower (PS) measures power. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
mJ relates to its own energy base unit by a factor of 0.001. PS relates to its own power base unit by a factor of 735.499.

Frequently asked questions
Can Millijoule be converted to Metric horsepower?
Not directly. Millijoule measures energy and Metric horsepower measures power. Converting between different physical quantities needs an extra physical relationship (such as area, distance, or time), not just a unit ratio.
What is Millijoule used for?
The Millijoule (mJ) is a unit of energy. Millijoule is 0.001 joule units.
What is Metric horsepower used for?
The Metric horsepower (PS) is a unit of power. Metric horsepower.
Why does the converter show an incompatible units message?
The Universal Converter only calculates a numeric result when both units share the same physical dimension. Since Millijoule and Metric horsepower don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Millijoule to instead?
Use another energy unit, such as one of the related Millijoule conversions linked below.
What should I convert Metric horsepower to instead?
Use another power unit, such as one of the related Metric horsepower conversions linked below.

About this conversion
This page compares Millijoule (mJ) and Metric horsepower (PS) within the engineering converter.
Millijoule is 0.001 joule units. Metric horsepower.
Because Millijoule measures energy and Metric horsepower measures power, the two units are not directly convertible: there is no fixed ratio that turns one into the other without additional information.
The calculator above will report that these units are not compatible. For a working result, choose two units from the same measurement family — see the related conversions below.
