About this calculator

Use this calculator for a solid block, a packed crate, or any rectangular prism whose bulk density you know. Enter length, width, height, and density in kg/m³.

Volume (m³) = length × width × height. Mass = volume × density. Length, width, and height can be entered in metres (m) or feet (ft). Mass is shown in kilograms (kg) or pounds (lb). Density stays in kg/m³.

This treats the box as solid. It does not deduct voids, packaging, or moisture.

Length: Long side, in m or ft.

Width: Short side, in m or ft.

Height: Height, in m or ft.

Density (kg/m³): Bulk density. Water is 1000; a packed crate is often much less.

Volume (m³): Volume in cubic metres.

Mass: Estimated mass from volume × density.
