What Is This Tool?
This converter transforms power values from kilocalorie (th)/second, a thermal power unit based on thermochemical calories, into pferdestärke (ps), a metric horsepower unit widely employed in automotive and mechanical power applications within German-speaking countries.
How to Use This Tool?
-
Enter the power value in kilocalorie (th)/second you wish to convert.
-
Select kilocalorie (th)/second as the input unit and pferdestärke (ps) as the output unit.
-
Click the convert button to see the equivalent value in Pferdestärke (ps).
Key Features
-
Converts thermal power units to mechanical horsepower units accurately.
-
Supports unit transformation between kilocalorie (th)/second and pferdestärke (ps).
-

-
Browser-based and easy to use with clear conversion formulas.
Examples
-
2 kilocalorie (th)/second converts to approximately 11.3773 pferdestärke (ps).
-
0.5 kilocalorie (th)/second converts to approximately 2.8443 pferdestärke (ps).
Common Use Cases
-
Expressing heat output ratings of heating devices using mechanical power equivalents.
-
Comparing thermal power from heating elements to engine power in automotive specifications.
-
Supporting HVAC system design and calorimetry reports with mechanical power context.
-
Referencing power output of older industrial machinery and small engines in regional units.
Tips & Best Practices
-
Always verify the unit conventions required in your region or industry before converting.
-
Use this tool when needing to compare thermal power measures to mechanical ratings.
-
Consider regulatory standards when employing the Pferdestärke unit, as it is non-SI.
-
Apply the exact conversion rate provided for consistent and reliable results.
Limitations
-
Pferdestärke (ps) is not an SI unit, so regional standards may affect usage acceptance.
-
Kilocalorie (th)/second is based on thermochemical calories that differ from other calorie definitions.
-
Conversions may be affected by rounding in practical calculations.
-
The tool does not provide historical or scientific context beyond the provided definitions.
Frequently Asked Questions

-
Where is Pferdestärke (ps) commonly used?
-
It is often used in German-speaking countries for expressing mechanical power in automotive specifications and older machinery.
-
Why convert kilocalorie (th)/second to Pferdestärke (ps)?
-
This facilitates comparing thermal power ratings to mechanical power ratings common in certain regional and industry contexts.
Key Terminology
-
Kilocalorie (th)/second
-
A unit of thermal power representing one thermochemical kilocalorie transferred per second, equal to exactly 4184 watts.
-
Pferdestärke (ps)
-
A metric horsepower unit used mainly in German-speaking countries for mechanical power, defined as 75 kilogram-force meter per second and equal to 735.49875 watts.
-
Thermochemical calorie
-
The base energy unit used for defining kilocalorie (th)/second, differing slightly from other calorie definitions.
