Cubic Inches to Cubic Feet Conversion
By Anne Marie Helmenstine, Ph.D.

Convert 3.5 cubic feet into cubic inches. When using a conversion factor, be sure the unit you are changing from gets canceled out.

You can multiply by the conversion factor:

3.5 cubic feet x 1728 cubic inches per cubic foot = 6048 cubic inches

Worked Example

You measure a box and find it is 2 foot long, 1 foot high, and 0.5 feet deep. The first step is to calculate the volume in cubic feet. The volume of the box is length x width x height so the volume of the box is:

2 x 1 x 0.5 = volume in cubic feet

1 cubic foot

Now, to convert this to cubic inches, you know there are 1728 cubic inches in 1 cubic foot:

1 cubic foot x (1728 cubic inches / 1 cubic foot) = volume in cubic inches

1 cubic foot x 1728 cubic inches/foot = volume in cubic inches

1728 cubic inches
