What is electric horsepower?

Electric horsepower is a power unit used to rate electric motors, defined as exactly 746 watts, representing mechanical work produced electrically.

When would I use attowatts as a power unit?

Attowatts are used to express very small power levels, such as those from ultra-sensitive detectors or nanoscale electronic devices.

Why convert from horsepower to attowatts?

This conversion helps compare large electric motor power to extremely small power scales used in advanced scientific research and specialized electronics.
