Concrete Calculator
Calculate Volume of Curb & Gutter
Calculator Use
Calculate volumes for concrete slabs, walls, footers, columns, steps, curbs and gutters. Enter dimensions in US units (inches or feet) 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. Also enter quantity and price to calculate total volume and cost of materials when you enter the price per cubic foot, price per cubic yard or price per cubic meter.
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".
- Choose Round Column (or Round Slab) on the calculator
- Enter Height 4 ft (or 48 in)
- Enter Diameter 10 in
- Calculate and the answer is 0.08 cubic yards for one concrete tube
- 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
Concrete Volume Formulas and Images for Different Concrete Forms
Square Slab
Calculate concrete volume of a square slab
Using measurements in feet:
Volume in Cubic Feet (ft3) = Width x Length x Depth
Volume in Cubic Yards (yd3) = Volume in Cubic Feet (ft3) / 27
Volume in Cubic Meters (m3) = Volume in Cubic Feet (ft3) x 0.0283
Round Slab
Calculate concrete volume of a round slab
Using measurements in feet:
Area of the Circle (ft2) = Pi x (Diameter/2)^2
Volume in Cubic Feet (ft3) = Depth x Area
Volume in Cubic Yards (yd3) = Volume in Cubic Feet (ft3) / 27
Volume in Cubic Meters (m3) = Volume in Cubic Feet (ft3) x 0.0283
Pi = 3.14
Wall
Calculate concrete volume of a wall
Using measurements in feet:
Volume in Cubic Feet (ft3) = Thickness x Length x Height
Volume in Cubic Yards (yd3) = Volume in Cubic Feet (ft3) / 27
Volume in Cubic Meters (m3) = Volume in Cubic Feet (ft3) x 0.0283
Footer
Calculate concrete volume of a footer
Using measurements in feet:
Volume in Cubic Feet (ft3) = Width x Length x Depth
Volume in Cubic Yards (yd3) = Volume in Cubic Feet (ft3) / 27
Volume in Cubic Meters (m3) = Volume in Cubic Feet (ft3) x 0.0283
Square Column
Calculate concrete volume of a square column
Using measurements in feet:
Volume in Cubic Feet (ft3) = Width x Length x Height
Volume in Cubic Yards (yd3) = Volume in Cubic Feet (ft3) / 27
Volume in Cubic Meters (m3) = Volume in Cubic Feet (ft3) x 0.0283
Round Column
Calculate concrete volume of a round column
Using measurements in feet:
Area of the Circle (ft2) = Pi x (Diameter/2)^2
Volume in Cubic Feet (ft3) = Height x Area
Volume in Cubic Yards (yd3) = Volume in Cubic Feet (ft3) / 27
Volume in Cubic Meters (m3) = Volume in Cubic Feet (ft3) x 0.0283
Pi = 3.14
Steps
Calculate concrete volume of steps
Using measurements in feet:
Number of Steps is the total number of steps including the platform.
We calculate the volume in sections from the ground to the top of each section.
The platform and each step are each sections.
Volume in Cubic Feet Under Platform =
Platform Depth x (Rise Height x Number of Steps) x Width
Counting steps starting at the bottom step and not including the platform we'll have Step Number 1, Step Number 2, Step Number 3, etc.
Volume in Cubic Feet Under Each Step =
Run Depth x (Rise Height x Step Number) x Width
Total up the step volumes then the total concrete you need is
Volume in Cubic Feet = Volume in Cubic Feet Under Platform + Volume in Cubic Feet Under Steps
Volume in Cubic Yards (yd3) = Volume in Cubic Feet (ft3) / 27
Volume in Cubic Meters (m3) = Volume in Cubic Feet (ft3) x 0.0283
Curbs & Gutters
Calculate concrete volume of curbs & gutters
Using measurements in feet:
We calculate the volume in sections from the ground to the top of each section. The Curb and Gutter are each a section.
Volume in Cubic Feet Under Curb =
Curb Depth x (Curb Height + Flag Thickness) x Length
Volume in Cubic Feet Under Gutter =
Gutter Width x Flag Thickness x Length
Volume in Cubic Feet = Volume in Cubic Feet Under Curb + Volume in Cubic Feet Under Gutter
Volume in Cubic Yards (yd3) = Volume in Cubic Feet (ft3) / 27
Volume in Cubic Meters (m3) = Volume in Cubic Feet (ft3) x 0.0283
