Here is the conversion factor and a worked example. Conversion Factor 1728 cubic inches = 1 cubic foot 0.000578704 cubic feet = 1 cubic inch Simple Example Convert 54.9 cubic inches into cubic feet. You can multiply by the conversion factor: 54.9 cubic inches x 0.000578704 cubic feet per cubic inch = 0.0318 cubic feet or you could simply divide the value in cubic feet by 1728: 54.9 cubic inches / 1728 cubic feet per cubic inch = 0.0318 cubic feet Worked Example You measure a box and find it is 12 inches long, 5 inches high, and 3 inches deep. The volume of the box is length x width x height so the volume of the box is: 12 x 5 x 3 = volume in cubic inches 180 cubic inches Now, to convert this to cubic feet, you know there are 1728 cubic inches in 1 cubic foot: 180 cubic inches x (1 cubic foot / 1728 cubic inches) = volume in cubic feet 180 cubic inches x 0.000578704 cubic feet/cubic inch = volume in cubic feet 0.1042 cubic feet Continue Reading
