Formula
Metric horsepower (PS) measures power, while Calorie (cal) measures energy. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
PS relates to its own power base unit by a factor of 735.499. cal relates to its own energy base unit by a factor of 4.184.

Frequently asked questions
Can Metric horsepower be converted to Calorie?
Not directly. Metric horsepower measures power and Calorie measures energy. Converting between different physical quantities needs an extra physical relationship (such as area, distance, or time), not just a unit ratio.
What is Metric horsepower used for?
The Metric horsepower (PS) is a unit of power. Metric horsepower.
What is Calorie used for?
The Calorie (cal) is a unit of energy. A thermochemical calorie is 4.184 joules.
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 Metric horsepower and Calorie don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Metric horsepower to instead?
Use another power unit, such as one of the related Metric horsepower conversions linked below.
What should I convert Calorie to instead?
Use another energy unit, such as one of the related Calorie conversions linked below.

About this conversion
This page compares Metric horsepower (PS) and Calorie (cal) within the engineering converter.
Metric horsepower. A thermochemical calorie is 4.184 joules.
Because Metric horsepower measures power and Calorie measures energy, 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.
