Pound Square Foot

lb·ft²

Definition

The pound square foot (lb·ft²) is a unit of moment of inertia in the imperial system. It is commonly used in US engineering and construction applications.

History/Origin

This unit combines the pound (mass) with the square foot, providing a measure of moment of inertia in the imperial system for larger scale applications.

Current Use

Widely used in US engineering, construction, and mechanical design where imperial units are preferred for moment of inertia calculations in larger systems.
