Area-to-volume conversions

Square feet measure flat area; cubic feet measure three-dimensional volume. You cannot convert one to the other without knowing the missing dimension. Our area-to-volume converters (square feet to cubic feet, cubic feet to square feet, linear feet to cubic feet) ask for the missing dimension and do the multiplication for you.

Weight conversions

Cubic feet describes volume; pounds and tons describe weight. The relationship between them depends on the material\u2019s density. Our cubic feet to pounds and cubic feet to tons converters include built-in density values for water, concrete, soil, mulch, gravel, and sand.

Choosing between calculators and converters

If you have length, width, and height, use a shape calculator. If you already have a cubic feet number and want to express it in different units, use a converter on this page. For project-specific answers (bag counts, truck sizing, tank gallons), see the use-case calculators.
