Convert kilogram square metre to kilogram force metre square second
Kilogram Square Metre
The kilogram square metre (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.
Kilogram-Force Metre Square Second
The kilogram-force metre square second (kgf·m·s²) is a technical unit of moment of inertia used in legacy engineering systems based on the kilogram-force. It arises from expressing Newton's second law for rotation using gravitational metric units, where force is measured in kilogram-force rather than newtons. One kgf·m·s² is equal to approximately 9.80665 kg·m².
