What Is This Tool?
This converter transforms force measurements from the pound foot per square second, a unit used in the foot–pound–second system to quantify force where pound is mass, into the SI derived unit hectonewton [hN]. It facilitates comparison and compatibility of force values between different unit systems.

Frequently Asked Questions
-
What is pound foot per square second as a force unit?
-
It is a force unit in the foot–pound–second system representing the force needed to accelerate a one-pound mass at one foot per second squared, commonly called the poundal.
-
Why convert pound foot/square second to hectonewton?
-
Converting to hectonewton standardizes force measurements into the SI system, making values compatible with modern engineering and scientific practices.
-
Where are hectonewtons commonly used?
-
Hectonewtons express moderate forces typically in the hundreds of newtons, such as in mechanical testing, tensile load specifications, and engineering datasheets.
Key Terminology
-
Pound foot/square second
-
A force unit in the FPS system equal to one pound mass accelerated at one foot per second squared, also known as the poundal.
-
Hectonewton [hN]
-
An SI derived force unit equal to 100 newtons, used for expressing forces around the hundred-newton magnitude.
-
FPS system
-
A system of units using foot, pound, and second as base units, where pound can represent mass.
