How to Use

Calculate volumes for concrete slabs, walls, footers, columns, steps, curbs and gutters. Enter dimensions in US units (inches or foot) or metric units (centimeters or meters) of your concrete structure to get the cubic yards value of the amount of concrete you will need to make this structure.

For Example

Let's say you have 50 round concrete form tubes, sonic tubes, Sonotubes or cement tubes that you need to fill. They are 4 feet in height and 10 inches in width (diameter), or 4' x 10".

1] Select “Hole, Column or Round Footings” Calculator
2] Enter Diameter 10 in
3] Enter Height 4 ft (or 48 in)
4] Enter Quantity 1
5] Click on Calculate buton

The answer will be 2.18 Cubic Feet Or 0.0808 Cubic Yards Or 0.0618 Cubic Meters
If Pre-Mixed Concrete*, It Is 290 Lbs Or 132 Kgs
If 60 Lbs Per Bag, It Is 4.84 Bags
If 80 Lbs Per Bag, It Is 3.63 Bags

Multiply 0.08 x 50 = 4 total cubic yards of concrete for 50 tubes.

Note that this calculation is the volume of your tubes only and does not account for any overflow or loss at the bottom of your tubes.
