gramme-millimètre carré

La gram carré millimeter (g·mm²) is a small unit of moment of inertia utilisé en precision engineering, micro-mechanics, and instrument design. It represents the rotational inertia of a one-gram mass located one millimeter from the axis of rotation. One gram carré millimeter est égal à 10⁻⁹ kg·m², the unité SI of moment of inertia. 


Kilogramme-mètre carré

La kilogram carré meter (kg·m²) is the unité SI of moment of inertia (aussi called rotational inertia), representing the resistance of a body to changes in its rotational motion. Il est défini comme the sum of the products of each mass element and the carré of its distance from the rotation axis. La kg·m² appears in rotational analogs of Newton's second law, où torque est égal à moment of inertia times angular acceleration.
