Kilogram Square Meter

kg·m²

Definition

The kilogram square meter (kg·m²) is the SI unit of moment of inertia, representing the resistance of a body to angular acceleration. It is calculated as the sum of the products of mass and the square of the distance from the axis of rotation.

History/Origin

Derived from the SI base units of mass (kilogram) and length (meter). It became the standard unit for moment of inertia in the International System of Units, fundamental in rotational dynamics and mechanical engineering.

Current Use

Widely used in mechanical engineering, physics, and robotics to calculate rotational motion, design rotating machinery, analyze gyroscopic effects, and solve problems involving angular momentum and torque.

Pound-Force Inch Square Second

lbf·in·s²

Definition

The pound-force inch square second (lbf·in·s²) is a unit of moment of inertia in the imperial gravitational system for smaller scale applications.

History/Origin

Based on the pound-force and inch, this unit provides moment of inertia measurements in the imperial gravitational system for smaller force-based calculations.

Current Use

Used in imperial gravitational engineering systems, US precision structural analysis, and applications where imperial force-based calculations are preferred for smaller systems.
