Frequently Asked Questions

What is a pound-force inch sq. second?
It is a unit of rotational moment of inertia in the English engineering system, equivalent to pound‑force multiplied by inch and second squared, representing mass times length squared through force and acceleration relations.

What does kilogram square millimeter measure?
Kilogram square millimeter is a derived metric unit measuring moment of inertia, indicating an object's resistance to angular acceleration based on mass times the square of distance.

Why convert between these two units?
Conversion helps translate rotational inertia data between customary English units and metric systems, facilitating accurate mechanical design, vibration analysis, and component comparison.

Key Terminology

Pound-force inch square second
A unit of moment of inertia in the English system, defined as pound-force times inch times second squared.
Kilogram square millimeter
