What Is This Tool?
This converter helps you change power values from electric horsepower, a unit used mainly for electric motors, to dekajoule per second, an SI-derived unit related to watts. It's designed to ease comparisons between U.S. customary power ratings and metric standards.
How to Use This Tool?
-
Enter the value in electric horsepower you need to convert
-
Choose dekajoule per second [daJ/s] as the target unit
-
View the converted power value instantly for your calculations or specifications
Key Features
-
Converts electric horsepower to dekajoule per second (daJ/s) with a fixed conversion rate
-
Supports power measurements common in industrial and electrical engineering fields
-
Ideal for comparing motor ratings, appliance specifications, and lab instruments
Examples
-
2 horsepower (electric) equals 149.2 dekajoule/second [daJ/s]
-
0.5 horsepower (electric) equals 37.3 dekajoule/second [daJ/s]
Common Use Cases
-
Checking power outputs on motor nameplates for pumps, fans, and compressors
-
Sizing electric controls like starters and power supplies for industrial motors
-
Converting motor ratings into SI-derived units for global standard compliance
Tips & Best Practices
-
Always verify units before converting to ensure correct input values
-
Use the conversion tool to compare motor power in watts-based units easily
-
Consider context-specific factors such as motor efficiency when interpreting results
Limitations
-
Electric horsepower is defined as exactly 746 watts, but actual motor power can vary with conditions
-
Dekajoule per second units are uncommon among general consumers and may need careful clarification
-
Conversion does not account for measurement precision or rounding differences in engineering data
Frequently Asked Questions
-
What is electric horsepower?
-
Electric horsepower is a unit of power used to rate electric motors, defined as exactly 746 watts.
-
Why use dekajoule per second instead of watts?
-
Dekajoule per second is equal to 10 watts and is useful to express power in SI units often preferred in scientific and engineering contexts.
-
Can the conversion rate change?
-
No, the conversion rate from electric horsepower to dekajoule per second is fixed at 1 horsepower equals 74.6 daJ/s.
Key Terminology
-
Electric horsepower
-
A power unit defined as exactly 746 watts used for rating electric motors and drives.
-
Dekajoule per second (daJ/s)
-
