# 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 (ft

^{3}) = Width x Length x Depth

Volume in Cubic Yards (yd

^{3}) = Volume in Cubic Feet (ft

^{3}) / 27

Volume in Cubic Meters (m

^{3}) = Volume in Cubic Feet (ft

^{3}) x 0.0283

### Round Slab

#### Calculate concrete volume of a round slab

Using measurements in feet:

Area of the Circle (ft

^{2}) = Pi x (Diameter/2)^2

Volume in Cubic Feet (ft

^{3}) = Depth x Area

Volume in Cubic Yards (yd

^{3}) = Volume in Cubic Feet (ft

^{3}) / 27

Volume in Cubic Meters (m

^{3}) = Volume in Cubic Feet (ft

^{3}) x 0.0283

Pi = 3.14

### Wall

#### Calculate concrete volume of a wall

Using measurements in feet:

Volume in Cubic Feet (ft

^{3}) = Thickness x Length x Height

Volume in Cubic Yards (yd

^{3}) = Volume in Cubic Feet (ft

^{3}) / 27

Volume in Cubic Meters (m

^{3}) = Volume in Cubic Feet (ft

^{3}) x 0.0283

### Footer

#### Calculate concrete volume of a footer

Using measurements in feet:

Volume in Cubic Feet (ft

^{3}) = Width x Length x Depth

Volume in Cubic Yards (yd

^{3}) = Volume in Cubic Feet (ft

^{3}) / 27

Volume in Cubic Meters (m

^{3}) = Volume in Cubic Feet (ft

^{3}) x 0.0283

### Square Column

#### Calculate concrete volume of a square column

Using measurements in feet:

Volume in Cubic Feet (ft

^{3}) = Width x Length x Height

Volume in Cubic Yards (yd

^{3}) = Volume in Cubic Feet (ft

^{3}) / 27

Volume in Cubic Meters (m

^{3}) = Volume in Cubic Feet (ft

^{3}) x 0.0283

### Round Column

#### Calculate concrete volume of a round column

Using measurements in feet:

Area of the Circle (ft

^{2}) = Pi x (Diameter/2)^2

Volume in Cubic Feet (ft

^{3}) = Height x Area

Volume in Cubic Yards (yd

^{3}) = Volume in Cubic Feet (ft

^{3}) / 27

Volume in Cubic Meters (m

^{3}) = Volume in Cubic Feet (ft

^{3}) 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 (yd

^{3}) = Volume in Cubic Feet (ft

^{3}) / 27

Volume in Cubic Meters (m

^{3}) = Volume in Cubic Feet (ft

^{3}) 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 (yd

^{3}) = Volume in Cubic Feet (ft

^{3}) / 27

Volume in Cubic Meters (m

^{3}) = Volume in Cubic Feet (ft

^{3}) x 0.0283
