Convert pound square inch to kilogram square meter
Pound Square Inch
The pound square inch (lb·in²) is a unit of moment of inertia in the US customary system equal to the product of one pound-mass and one square inch. It is often used for smaller rotating components in mechanical engineering, such as electric motors and actuators. One lb·in² equals 1/144 lb·ft², or approximately 2.92640 × 10⁻⁴ kg·m².
Kilogram Square Meter
The kilogram square meter (kg·m²) is the SI unit of moment of inertia (also called rotational inertia), representing the resistance of a body to changes in its rotational motion. It is defined as the sum of the products of each mass element and the square of its distance from the rotation axis. The kg·m² appears in rotational analogs of Newton's second law, where torque equals moment of inertia times angular acceleration.
