What Is This Tool?
This converter helps you transform values of moment of inertia from ounce square inch [oz*in^2], a unit combining mass and length squared, into ounce-force inch sq. second, a related imperial unit involving force, length, and time dimensions. It is intended for use in mechanical design, calibration, and analysis of small rotating parts.
How to Use This Tool?
-
Enter the value in ounce square inch [oz*in^2].
-
Select the target unit as ounce-force inch sq. second.
-
Click convert to get the equivalent moment of inertia in the new unit.
Key Features
-

Limitations
-
Units are non-SI and mainly suited for US customary unit systems.
-
Conversions may be impacted by measurement precision of small values.
-
Care is needed when interfacing with SI-based systems to maintain consistency.
Frequently Asked Questions
-
What does ounce square inch measure?
-
It is a unit of mass moment of inertia that combines ounces of mass and inches squared to express an object's resistance to angular acceleration.
-
When should I use ounce-force inch sq. second?
-
Use this unit for precision analysis of rotational inertia in small rotors or components where force, length, and time are involved.
-
Is this conversion applicable to SI units?
-
This conversion is mostly relevant in US customary contexts; conversion to SI units requires separate formulas.
Key Terminology
-
Ounce square inch [oz*in^2]
-
A non-SI unit of mass moment of inertia equal to one ounce of mass multiplied by the square of one inch, expressing resistance to angular acceleration.
-
Ounce-force inch sq. second
-
A unit measuring moment of inertia as an ounce-force multiplied by an inch and by a second squared, used in precision rotational dynamics.
