Convert pound force foot square second to kilogram square meter
Pound-Force Foot Square Second
The pound-force foot square second (lbf·ft·s²) is an imperial unit of moment of inertia equivalent to the slug·ft², the standard unit in the foot-pound-second system. It is used in aerospace, automotive, and mechanical engineering in the United States for expressing the rotational inertia of large components. One lbf·ft·s² equals approximately 1.35582 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.
