Quote plate tonnage with a single pass.

Input dimensions once and get a clean weight output with formula traceability.

Weight mode length, width, and direct thickness accept mm, cm, m, in, or ft independently; legacy requests default to mm for metric and in for imperial. Inverse mode returns length in mm or in based on result units.

Material grade selection supplies reference density for mass estimation only and does not verify grade certification or structural suitability.

Quantity and allowance are applied to order weight.

Supports catalog or custom material density with kg/m³ and lb/in³ input.

Inverse mode solves required plate length from a target weight.
