Volume calculations for concrete footing forms:
| Model | Volume of concrete | Model | Volume of concrete |
| BF20 | 1.75 cubic feet | BF24 | 2.50 cubic feet |
| BF28 | 3.25 cubic feet | BF36 | 6 cubic feet |
| BFT10 | 2.18 cubic feet |
Concrete volume calculations for sono tubes:
| Tube Diameter | 6" | 8" | 10" | 12" | 14" | 18" |
| Volume of Concrete / Unit of Tube Length | ||||||
| cu.ft. / ft. | 0.196 | 0.349 | 0.545 | 0.785 | 1.067 | 1.767 |
| cu.in. / ft. | 339.3 | 603.07 | 941.76 | 1356.48 | 1843.78 | 3053.38 |
| cu.metres / meter | 0.018 | 0.032 | 0.050 | 0.071 | 0.097 | 0.161 |
Note: Volume is per foot of construction tube. For example:
-
10" construction tube 6 feet long:
6 ft x 0.545 cu.ft. / ft. (of tube length) = 3.27 cubic feet
6 ft. x 941.76 cu.in. / ft. (of tube length) = 5,650.56 cubic inch
1.8288 m. x 0.051 cu.m. / meter (of tube length) = 0.095 cubic metres
-
Using both Bigfoot Systems Footing Forms and construction tubes combined -
Model BF24 with a 10 inch tube 6 feet long:
6 ft. x 0.545 cu.ft. + 2.50 cu.ft. = 5.77 cubic feet (0.163 cubic meters) of concrete
