What Is This Tool?
This converter transforms power values from Pferdestärke (ps), a traditional metric horsepower unit widely used in automotive contexts in German-speaking regions, into kilojoule per minute (kJ/min), which expresses the rate of energy transfer over time. It is useful for translating mechanical power figures into an energy-based rate useful in physiology, calorimetry, and engineering.
How to Use This Tool?
-
Enter the power value measured in Pferdestärke (ps).
-

Examples
-
2 Pferdestärke (ps) equals 88.25985 kilojoule per minute (kJ/min).
-
0.5 Pferdestärke (ps) equals 22.0649625 kilojoule per minute (kJ/min).
Common Use Cases
-
Converting engine power ratings from PS into energy rates for automotive analysis.
-
Measuring metabolic energy expenditure in exercise physiology using kJ/min.
-
Describing heating or cooling rates in laboratory calorimetry where energy per minute is relevant.
-
Evaluating power consumption of small appliances expressed in energy transfer terms.
Tips & Best Practices
-
Ensure input values are accurate for reliable conversion results.
-
Use the conversion for comparing mechanical power in PS to energy rates relevant in physiology and calorimetry.
-
Be aware of the unit context since Pferdestärke is non-SI and regionally specific.
-
Consult technical documents to confirm unit conventions are appropriate for your application.
Limitations
-
Pferdestärke (PS) is a non-SI unit and mainly used regionally, limiting global standard compatibility.
-
Kilojoule per minute (kJ/min) conveys energy over time and may be less intuitive for instantaneous power readings without conversion.
-
Some rounding impact on precision can occur when converting between these units.
Frequently Asked Questions
-
What does Pferdestärke (PS) represent?
-
Pferdestärke (PS) means 'horse strength' and is a metric horsepower unit used primarily in German-speaking countries to express mechanical power.
-
Why convert PS to kilojoule per minute?
-
Converting PS to kilojoule per minute helps express mechanical power as an energy transfer rate per minute, useful in physiology, calorimetry, and other fields.
-
Is Pferdestärke an SI unit?
-
No, Pferdestärke is not part of the International System of Units; it remains common in regional automotive and historical measurements.
Key Terminology
-
Pferdestärke (PS)
-
