What Is This Tool?
This converter allows you to translate power values from joule per hour (J/h), a unit reflecting energy transfer over one hour, into foot pound-force per second (ft·lbf/s), an imperial unit representing mechanical power. It is designed to assist with engineering calculations and energy balance conversions between SI and customary units.
How to Use This Tool?

-
High-precision instruments might be needed to measure or verify these small power quantities
-
Conversion errors can occur if the temporal basis or unit type is misunderstood
Frequently Asked Questions
-
What does joule/hour measure in terms of power?
-
Joule per hour measures the rate of energy transfer over one hour, representing very low continuous power levels.
-
Why convert joule/hour to foot pound-force per second?
-
Conversion helps express power in imperial units common in mechanical contexts, facilitating engineering calculations involving force and displacement in feet and pounds-force.
-
Are there any challenges when converting between these units?
-
Yes, differences in unit systems and the time basis require careful interpretation to avoid errors, especially since joule/hour values are very small.
