What Is This Tool?
This tool converts power values from electric horsepower, a unit used to rate electric motors, to milliwatts, which measure low power levels typically found in electronic devices.
How to Use This Tool?
-
Enter the power value in electric horsepower
-
Select 'horsepower (electric)' as the input unit and 'milliwatt [mW]' as the output unit
-
Click convert to see the equivalent power in milliwatts
Key Features
-
Converts between electric horsepower and milliwatts accurately
-
Ideal for comparing motor power ratings with small electronic components
-
Browser-based and easy to use with no installation required
Examples
-
2 horsepower (electric) equals 1,492,000 milliwatt [mW]
-
0.5 horsepower (electric) equals 373,000 milliwatt [mW]
Common Use Cases
-
Identifying motor output power on nameplates for pumps and compressors
-
Sizing electrical components like motor controllers and starters
-
Comparing power ratings between electric motors and electronic devices
Tips & Best Practices
-
Understand the context since electric horsepower and milliwatt measure different aspects of power
-
Use the converter to facilitate power management across different equipment types
-
Cross-check with equipment specifications for efficiency factors
Limitations
-
Conversion does not account for operational losses or efficiency
-
Horsepower ratings reflect mechanical power while milliwatts often represent electrical or optical power
-
Always consider the specific application context when interpreting results
Frequently Asked Questions
-
What is electric horsepower used for?
-
Electric horsepower is used to rate the power output of electric motors and drives, especially in industrial equipment like pumps and compressors.
-
Why convert horsepower to milliwatts?
-
Converting horsepower to milliwatts helps compare large motor power levels with low power electronic devices for system integration and precise power management.
-
Does this conversion consider efficiency losses?
-
No, the conversion ignores efficiency and operational conditions; it is a direct unit conversion between mechanical and electrical power units.
Key Terminology
-
Electric Horsepower
-
A unit of power equal to 746 watts, used to rate electric motor power output.
-
Milliwatt [mW]
-
One thousandth of a watt, measuring small power levels for electronic, optical, and radio-frequency devices.
