-
Errors may arise from imprecise conversion between FPS and SI units
-
Relevant mainly for legacy data or niche applications involving FPS units
Frequently Asked Questions
-
What does pound foot per square second measure?
-
It is a unit of force in the FPS system representing the force required to accelerate a one pound mass at one foot per second squared, commonly called the poundal.
-
Why convert pound foot/square second to meganewton?
-
Converting to meganewton expresses the force in SI units, which are standard for large forces in scientific and engineering applications.
-
Is pound foot/square second commonly used today?
-
No, it is mostly found in legacy data or older engineering documents and is rarely used in modern practice.
Key Terminology
-
Pound foot per square second (poundal)
-
A force unit in the FPS system defined as the force needed to accelerate 1 pound mass at 1 foot per second squared.
-
Meganewton (MN)
-
An SI derived unit of force equal to one million newtons, used for very large forces.
-
FPS system
-
The foot–pound–second system of units where pound indicates a mass rather than weight.
