Estimate pipe weight from measured walls.
Use actual outside diameter and wall thickness to calculate hollow cross-section, weight per foot, piece weight, and batch cost.

Transparent calculation
Metal area = π ÷ 4 × (outside diameter² − inside diameter²).
Inside diameter is outside diameter minus twice the measured wall. Metal area then multiplies by length, quantity, and entered density.
