What units are used to measure volume?

The correct measurement for volume is cubic feet. Volume measures how much space an object or substance occupies, and it is expressed in three-dimensional units. Cubic feet represents a volume that is created by a cube with each side measuring one foot in length.

Other units of measurement for volume, such as liters, are also valid; however, cubic feet is particularly common in HVAC applications because it aligns closely with the way spaces are designed and managed in buildings.

Square feet, on the other hand, measures area, which is a two-dimensional metric, not addressing the height or depth required for a volume calculation. Meters is a linear measurement for length and, similarly to square feet, does not capture the three-dimensional aspect of volume. Thus, cubic feet is the correct choice for accurately measuring volume.
