Frequently Asked Questions
-
What does pound-force inch sq. second measure?
-
It measures rotational moment of inertia in the English engineering system, combining force, length, and time squared units.
-
Why convert to gram square centimeter?
-
Gram square centimeter is used in the cgs system and common in precision instrument design and laboratory calculations involving small rotating parts.
-
Can this converter be used for large rotating systems?
-
This converter is intended mainly for small to medium-sized systems; very large systems may require different unit conventions.
Key Terminology
-
Pound-force inch sq. second
-
A unit of rotational moment of inertia in English engineering, equal to pound-force times inch times second squared, representing mass times length squared via force-based mass.
-
Gram square centimeter
-
A cgs unit of moment of inertia, equal to mass in grams multiplied by distance squared in centimeters, used to quantify resistance to rotational acceleration.
