What Is This Tool?
This tool allows users to convert power values from hectowatts, a unit equal to 100 watts commonly used for small electrical loads, to electric horsepower, a unit frequently applied in rating electric motors and drives. It helps bridge SI units and U.S. engineering standards for power measurements.
How to Use This Tool?
-
Enter the power value in hectowatts you wish to convert.
-
Select 'hectowatt [hW]' as the source unit and 'horsepower (electric)' as the target unit.
-
Submit to receive the converted power value in electric horsepower.
-
Review results for use in industrial motor sizing or equipment documentation.
Key Features
-
Quickly converts power from hectowatt (hW) to electric horsepower (hp).
-
Utilizes the exact conversion factor based on standardized unit definitions.
-
Ideal for motor nameplate data interpretation and equipment specification.
-
Supports comparisons between SI units and traditional horsepower units.
-
Browser-based and easy to use without special software installation.
Examples
-
1 hW equals approximately 0.1340482574 electric horsepower.
-
To convert 5 hW, multiply 5 by 0.1340482574 to get about 0.670241287 hp (electric).
Common Use Cases
-
Comparing smaller power ratings expressed in watts to electric horsepower for industrial equipment.
-
Interpreting motor nameplate outputs for pumps, fans, and compressors.
-
Sizing and selecting motor controllers and electrical supplies for machinery.
-
Preparing technical specifications and invoices that require horsepower units.
Tips & Best Practices
-
Ensure the correct unit is selected when entering values for accurate conversion.
-
Use conversions to compare power ratings across different measurement systems.
-
Check motor nameplates carefully to apply the appropriate unit standards.
-
Consider regional differences in horsepower definitions when relevant.
-
Apply conversions consistent with standardized motor and electrical specifications.
Limitations
-
The tool assumes standard unit definitions; alternative horsepower standards may cause slight discrepancies.
-
Conversions are designed for typical power ranges; very large values may need attention to numerical precision.
-
Regional variations in horsepower units are not accounted for in this conversion.
Frequently Asked Questions
