What is a femtowatt used to measure?

A femtowatt quantifies extremely small energy transfer rates, often in nanoscale systems, sensitive measurements, and low-power electronic devices.

Why convert femtowatts to pound-foot/hour?

This conversion helps express very small electrical or radiant power levels as mechanical power rates in legacy imperial units for specialized or historic uses.

Is pound-foot per hour commonly used in modern power measurements?

No, it is mostly found in historical documentation or specialized fields involving slow mechanical work and is rarely used in current engineering.
