What is an erg per second (erg/s)?

An erg per second is a CGS unit of power representing one erg of energy transferred each second, equivalent to 1×10⁻⁷ watts in SI units.

Where is Pferdestärke (PS) typically used?

PS is a metric horsepower unit primarily used in German-speaking countries for describing mechanical power like engine outputs.

Why are erg/s values so small when converted to PS?

Because erg/s is a very small unit of power, converting it to PS results in extremely small fractional values, limiting its practicality in everyday mechanical power contexts.

What Is This Tool?

This unit converter allows you to translate power values expressed in erg per second (erg/s), a CGS-system unit commonly used in astrophysics and older scientific literature, into Pferdestärke (PS), a metric horsepower unit used primarily in German-speaking countries for mechanical power ratings.

How to Use This Tool?

Enter the power value in erg per second (erg/s) that you want to convert.
Select the target unit as Pferdestärke (PS) from the options.
Click the convert button to see the corresponding power value in PS.
Interpret the result considering that erg/s values produce very small fractions in PS.
Use the output for automotive specs, historical engine ratings, or astrophysical comparisons.

Key Features

Converts small CGS power units (erg/s) to metric horsepower units (PS).
Based on precise conversion rates bridging CGS and metric systems.
Useful for translating astrophysical power measurements into practical vehicle and machinery power ratings.
Browser-based and easy to access without installation.
Supports unit conversions relevant to scientific research and regional automotive specifications.

Examples

1,000,000 erg/s converts to 0.00013596 PS.
10,000,000 erg/s converts to 0.00135962 PS.

Common Use Cases

Expressing luminosity and radiative power in astrophysics research using erg/s values.
Translating theoretical CGS unit power values into commonly understood mechanical power units in German automotive contexts.
Presenting engine power in car and motorcycle specifications within German-speaking markets.
Providing power ratings in vehicle manuals, brochures, and resale listings using PS units.
Describing output of older industrial machinery when regional or historical units apply.

Tips & Best Practices

Remember that erg/s is a very small power unit, so converted values in PS will be fractional and often very small.
Consider regional preferences when using PS units, as it is mainly common in some European countries.
Check if PS is appropriate for your audience, especially if SI units are preferred in scientific contexts.
Use this conversion for bridging older scientific data with modern mechanical power ratings.
Be mindful that PS is not an SI unit and is mostly of historical or regional relevance.

Limitations

Due to the tiny magnitude of erg/s, the conversion leads to very small fractional PS values, which may be impractical for everyday power ratings.
Pferdestärke (PS) is not an SI unit and is mostly used regionally, limiting its universal applicability.
Precision issues might arise when converting typical engine powers given the large difference in scale between erg/s and PS.
Conversions should take into account regional unit preferences where PS is accepted or standard.
