What Is This Tool?
This converter transforms power measurements from electric horsepower, commonly used for rating electric motors, into terajoule per second, a unit for extremely large power flows. It aids in comparing motor outputs to high-scale energy system values.
How to Use This Tool?
-
Enter the power value in electric horsepower that you want to convert
-
Select 'horsepower (electric)' as the source unit and 'terajoule/second [TJ/s]' as the target unit
-
Click the convert button to see the equivalent power in terajoules per second
Key Features
-
Converts between electric horsepower and terajoule per second accurately using defined rates
-
Simple, browser-based interface ideal for engineers and planners
-
Supports power rating translations from individual motors to national grid scales
Examples
-
100 horsepower (electric) converts to 7.46e-8 terajoule/second
-
1,000,000 horsepower (electric) converts to 7.46e-4 terajoule/second
Common Use Cases
-
Interpreting electric motor power ratings for industrial equipment
-
Sizing motor controllers and electrical supply components
-
Estimating large-scale energy flows like national grid outputs
-
Bridging power scale from motors to terawatt-level energy generation
Tips & Best Practices
-
Use the converter for translating motor ratings to very large power units used in energy modeling
-
Be mindful of the unit scale difference to understand practical applicability
-
Confirm that terajoule/second measurement suits your analysis context before converting
Limitations
-
The conversion spans many orders of magnitude, limiting precision for small horsepower values
-
Terajoule per second is not practical for everyday motor power ratings
-
Conversion should be applied carefully based on scale and intended use
Frequently Asked Questions
-
What is electric horsepower?
-
Electric horsepower is a power unit for rating electric motors, defined as exactly 746 watts.
-
What does terajoule per second represent?
-
Terajoule per second is a unit of power representing one trillion joules transferred each second, equivalent to one terawatt.
-
When should I convert horsepower (electric) to terajoule/second?
-
This conversion is useful for comparing typical motor outputs to large-scale power flows like those in national grids or energy system models.
Key Terminology
-
Horsepower (electric)
-
A unit of power rating electric motors, defined as exactly 746 watts.
-
Terajoule per second [TJ/s]
-
A unit of power equal to the energy rate of one trillion joules per second, equivalent to one terawatt.
-
Conversion Rate
-
The factor used to translate horsepower (electric) values into terajoule per second: 1 horsepower (electric) = 7.46e-10 TJ/s.
