Convert pound square foot to kilogram square meter
Pound Square Foot
The pound square foot (lb·ft²) is a unit of moment of inertia in the US customary system, representing the product of a mass in pounds-mass and a distance squared in square feet. It is widely used in mechanical and aerospace engineering in the United States. One lb·ft² is equal to approximately 0.0421401 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.
