Kilogram Square Meter

kg·m²

Definition

The kilogram square meter (kg·m²) is the SI unit of moment of inertia, representing the resistance of a body to angular acceleration. It is calculated as the sum of the products of mass and the square of the distance from the axis of rotation.

History/Origin

Derived from the SI base units of mass (kilogram) and length (meter). It became the standard unit for moment of inertia in the International System of Units, fundamental in rotational dynamics and mechanical engineering.

Current Use

Widely used in mechanical engineering, physics, and robotics to calculate rotational motion, design rotating machinery, analyze gyroscopic effects, and solve problems involving angular momentum and torque.

Gram Square Millimeter

g·mm²

Definition

The gram square millimeter (g·mm²) is a unit of moment of inertia for very small rotating components. It is used in micro-mechanical and precision applications.

History/Origin

Based on the gram and square millimeter, this unit provides moment of inertia measurements for micro-scale mechanical systems and precision engineering applications.

Current Use

Used in micro-mechanical systems, precision instruments, small electronic components, and applications requiring very fine-scale moment of inertia calculations with gram-mass units.
