Frequently Asked Questions
-
What does one ounce-force inch sq. second represent?
-
It is a moment of inertia unit defined as an ounce-force multiplied by an inch and by second squared, measuring resistance to angular acceleration.
-
Why convert ounce-force inch sq. second to pound-force inch sq. second?
-
Because it facilitates translation of very small rotational inertia values into a larger unit base suitable for engineering design and analysis.
-
Can this conversion be used for precision instruments without any adjustment?
-
This conversion provides a basic value, but precision instruments may require higher accuracy beyond simple conversion.
Key Terminology
-
Ounce-force inch sq. second
-
