What Is This Tool?
This tool converts power values from electric horsepower to erg per second (erg/s), enabling translation between common engineering units and CGS units often used in astrophysics and theoretical physics.
How to Use This Tool?
-
Enter the numeric value in electric horsepower you wish to convert.
-
Select 'horsepower (electric)' as the input unit and 'erg/second (erg/s)' as the output unit.
-
Click the convert button to get the equivalent power in erg per second.
Key Features
-
Converts electric horsepower to erg/second accurately.
-
Designed for power unit conversions in engineering and scientific contexts.
-
Easy to use online interface for quick calculations.
-
Helps compare electric motor power ratings with astrophysical power measurements.
Examples
-
2 horsepower (electric) converts to 14,920,000,000 erg/second (erg/s).
-
0.5 horsepower (electric) converts to 3,730,000,000 erg/second (erg/s).
Common Use Cases
-
Interpreting motor output power from industrial equipment nameplates.
-
Sizing electrical supply and control devices for motors using horsepower ratings.
-
Converting power data to CGS units for astrophysics research and radiative energy reporting.
-
Comparing and reconciling engineering power information with scientific literature using CGS units.
Tips & Best Practices
-
Ensure input values are in electric horsepower for accurate conversion results.
-
Use this conversion mainly when working with astrophysics or theoretical physics contexts requiring CGS units.
-
Be aware that erg/second values may be very large due to the small size of this unit relative to horsepower.
-
Double-check final converted values before using them in technical documentation or calculations.
Limitations
-
Erg/second is extremely small compared to horsepower, resulting in very large converted numbers.
-
CGS units like erg/s are not commonly used in modern engineering practice and are primarily for specialized scientific or historical use.
Frequently Asked Questions
-
What is electric horsepower?
-
Electric horsepower is a power unit used to rate electric motors, defined exactly as 746 watts in U.S. engineering standards.
-
Why convert horsepower to erg/second?
-
Converting to erg/second allows users to compare motor power ratings with power values expressed in CGS units commonly used in astrophysics and theoretical physics.
-
Is erg/second widely used in engineering?
-
No, erg/second is mostly obsolete in engineering and mainly used in specific scientific fields or older literature.
Key Terminology
