Dimensional Weight Calculator

Enter package dimensions in inches to estimate cubic feet and dimensional weight. This tool follows Numode’s method with step-by-step rounding.

DIM factor: 15 lb/ft³
Rounding: 2 decimals after each step (ft³ → DIM lb)

A (Length, in)

B (Width, in)

H (Height, in)

Measure to the nearest inch. Volume for boxes: A × B × H. Convert to ft³ by ÷ 1728, then multiply by the DIM factor. Round at each step.

D (Diameter, in)

H (Height, in)

For cylinders, use the diameter as both length and width: D × D × H. Convert to ft³ by ÷ 1728, apply DIM factor, and round at each step.

L (Length, in)

W (Width, in)

H (Height, in)

Place the package in a corner in the load position, hold a straight edge at 90° to form a bounding box, then measure L × W × H to the nearest inch.

Load Example Case (16 × 14 × 14 in)

This reproduces: 3136 in³ → 1.81 ft³ → 27.15 lb dimensional.
