Calculate Box Volume in Cubic Feet from Inches

Volume

0.56 ft³

Volume (cubic inches) 960 in³

Girth + Length 48.0 in

This calculator quickly determines the volume of a box in cubic feet using its dimensions in inches. It is an essential tool for shipping, logistics, and storage planning, helping to estimate space requirements and shipping costs. In addition to volume, it also calculates the "Girth + Length," a common measurement used by carriers to define package size limits.

How to Use

Simply enter the length, width, and height of your package in inches into the corresponding fields. The calculator will instantly display the volume in both cubic feet (ft³) and cubic inches (in³).

Formula

The calculation is a two-step process. First, the volume is found in cubic inches:

Volume (in³) = Length (in) × Width (in) × Height (in)

Next, this value is converted to cubic feet by dividing by 1728 (since 1 ft³ = 12³ in³ = 1728 in³):

Volume (ft³) = Volume (in³) / 1728

Example

Consider a box with the following dimensions:

  • Length = 12 in
  • Width = 10 in
  • Height = 8 in

The calculation steps are:

  1. Calculate the volume in cubic inches: 12 × 10 × 8 = 960 in³
  2. Convert the result to cubic feet: 960 / 1728 = 0.56 ft³

The volume of the box is 0.56 cubic feet.
