What does horsepower measure?

Horsepower is a traditional non-SI power unit used to express the rate of work, commonly defined as 550 foot-pounds per second or approximately 745.7 watts.

What is a microjoule per second used for?

A microjoule per second quantifies very small continuous power levels, often in electronic devices, photonics, and energy-harvesting applications.

Why convert horsepower to microjoule per second?

Converting horsepower to microjoule per second helps compare large mechanical power outputs to tiny power levels in electronic and optical systems.
