What is electric horsepower defined as?

Electric horsepower is defined as exactly 746 watts, representing the power output of an electric motor equivalent to one mechanical horsepower.

What does picojoule per second measure?

Picojoule per second measures very small continuous power levels equal to 10⁻¹² joules per second, commonly used in microelectronics and photonics.

Why convert from horsepower to picojoule/second?

Converting helps compare or integrate power specifications from large industrial motors to ultra-low-power electronic circuits and devices.

What Is This Tool?

This tool converts power measurements from electric horsepower, a unit used to rate electric motors, to picojoule per second, a very small power unit used in microelectronics and photonics. It helps translate between large-scale mechanical power and ultra-low power levels.

How to Use This Tool?

Enter the power value in electric horsepower you want to convert.
Select picojoule/second [pJ/s] as your target unit.
Click the convert button to see the equivalent power in picojoule per second.
Review and use the converted value for your technical or engineering requirements.

Key Features

Converts electric horsepower (exactly 746 watts) to picojoule per second (10⁻¹² watts).
Useful for comparing power ratings from industrial motors to ultra-low-power circuits.
Browser-based and easy to use with instant results.
Supports applications in electrical engineering, photonics, and micro/nanoelectronics.

Examples

2 horsepower (electric) converts to 1.492 × 10^15 picojoule/second [pJ/s].
0.5 horsepower (electric) converts to 3.73 × 10^14 picojoule/second [pJ/s].

Common Use Cases

Interpreting motor nameplate power ratings in microelectronics units.
Sizing motor controllers and electrical supply capacities for industrial equipment.
Specifying power draw for ultra-low-power microcontrollers and sensors.
Reporting optical power in sensitive photonic detectors and single-photon systems.
Converting energy-per-operation rates to power for digital circuit analysis.

Tips & Best Practices

Use the tool to bridge power specifications across very different scales effectively.
Verify unit selections carefully to avoid confusion given large differences in scale.
Remember the conversion yields very large numbers that may require appropriate formatting.
Apply the converted values for continuous power measurements rather than transient peaks.

Limitations

The conversion produces extremely large numeric results due to scale differences.
Numerical precision errors may arise in calculations or display.
Units measure continuous power and may not represent transient or peak values accurately.
