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

An erg per second is a unit of power in the CGS system representing one erg of energy transferred each second. It equals 1×10⁻⁷ watts in SI units.

How is electric horsepower defined for this conversion?

Electric horsepower is defined as exactly 746 watts and is used to rate electric motors and drives in engineering applications.

Why might large erg/s values be necessary for conversion?

Because erg/second is a very small power unit, significant magnitude in erg/s is needed to reach even a fractional amount of electric horsepower.

What Is This Tool?

This converter allows users to transform power values measured in erg per second (erg/s), a CGS system unit commonly used in scientific contexts, into electric horsepower, a standard unit for rating electric motors and related machinery.

How to Use This Tool?

Enter the power value in erg/second (erg/s) into the input field.
Select erg/second as the source unit and horsepower (electric) as the target unit.
Click the convert button to see the equivalent power in electric horsepower.
Review the converted result and use it for your engineering or scientific calculations.

Key Features

Accurate conversion between erg/second and electric horsepower using fixed definitions.
Supports power unit conversions relevant to fields like astrophysics and electrical engineering.
Provides clear unit definitions and practical use cases for each measurement.
Browser-based and easy to use with simple input and output steps.

Examples

1,000,000 erg/s converts to approximately 1.3404825737265e-4 horsepower (electric).
10,000,000 erg/s converts to around 0.0013404825737265 horsepower (electric).

Common Use Cases

Expressing the luminosities and radiative power of astronomical objects in astrophysics.
Reporting power values in CGS-based theoretical calculations and older scientific literature.
Interpreting motor nameplates and specifications for pumps, fans, and compressors.
Sizing motor controllers, starters, and electrical supply capacities in industrial contexts.
Comparing equipment ratings or preparing specifications and invoices involving different power units.

Tips & Best Practices

Always verify the input unit matches erg/second when converting to electric horsepower.
Use large erg/second values to avoid extremely small output in horsepower due to unit scale differences.
Cross-check converted values especially when used for technical specifications and engineering documentation.
Understand the context of unit usage—erg/second is ideal for scientific studies, while electric horsepower suits practical engineering ratings.

Limitations

Erg/second is much smaller than electric horsepower, requiring large inputs for meaningful horsepower results.
Precision of conversion depends on the fixed watt definition underlying the electric horsepower standard.
Erg/second is mostly relevant for theoretical or scientific purposes and may not be practical for general engineering measurements.
