What does one electric horsepower represent?

One electric horsepower is defined as exactly 746 watts and is used to rate electric motors and drives.

Is the conversion useful for direct equipment application?

No, because the units measure very different power scales, the conversion is more suited for comparison rather than direct use.

What Is This Tool?

This conversion tool helps translate power values from electric horsepower, a unit used for rating electric motors, to microjoule per second (µJ/s), which measures very small continuous power levels in microelectronics and photonics.

How to Use This Tool?

Enter the value in horsepower (electric) you want to convert.
Select horsepower (electric) as the input unit and microjoule/second [µJ/s] as the output unit.
Execute the conversion to get the equivalent power in microjoule/second.

Key Features

Converts electric horsepower (exactly 746 watts) to microjoule/second (µJ/s).
Supports comparisons between industrial motor ratings and ultra-low-power devices.
Provides clear conversion with a precise fixed ratio: 1 electric horsepower = 746,000,000 µJ/s.
Useful in engineering, microelectronics, and photonics applications.

Examples

2 horsepower (electric) converts to 1,492,000,000 microjoule/second [µJ/s].
0.5 horsepower (electric) converts to 373,000,000 microjoule/second [µJ/s].

Common Use Cases

Interpreting motor output ratings on pumps, fans, and compressors.
Sizing control equipment and electrical supply for industrial motors.
Comparing power consumption of ultra-low-power microcontrollers and IoT sensors.
Measuring optical power in photonics and microscopy devices.
Evaluating power from tiny energy harvesting systems like micro solar cells.

Tips & Best Practices

Double-check the input units to avoid confusion between mechanical and electric horsepower.
Use this conversion primarily for scale comparison rather than direct power application.
Keep in mind large numerical results when converting from high power to micro-scale units.
Utilize the tool for technical specifications and precise power measurement comparisons.

Limitations

Conversion results may yield very large numbers due to the scale difference.
The units reflect vastly different power magnitudes, limiting direct practical use.
Not intended for direct application but for cross-scale power rating comparisons.
