# Metric Stadium Slab Concrete

Calculate the amount of concrete you need for pouring for a stadium shaped slab, using metric meassurements

#### Calculation

- enter length A in metres
- length B in meters
- the depth of the slab in millimetres

#### Results

- the area of the stadium in square metres
- the perimeter of the stadium in lineal metres
- the amount of concrete needed in in cubic metres
- in cubic yards
- in cubic feet

##### Formulas

Area = π * r² + 2 * r * a
Perimeter = 2 * (πr + a)
where π = 3.14159265
r = the radius of the half-circle
a = the length of the rectangle shape in between the half circles

##### Conversions

one cubic millimetre (mm³) = 0.000000001 cubic metres (m³)
one cubic millimetre (mm³) = 0.0000000353146667214886 cubic feet (ft³)
one cubic millimetre (mm³) = 0.00000000130795061931439 cubic yards (yd³)

To convert cubic metres to cubic feet, multiply cubic metres by 35.314666721488
To convert cubic metres to cubic yards, multiply cubic metres by 1.30795061931439

### When Ordering Concrete

This concrete calculator will help you in estimating the amount of concrete needed for your project. The amount given as needed does not include any waste. Depending on your job, we recommend adding anywhere from an extra 4% to 10% to your concrete required calculation to make sure you have enough concrete to finish the job. Ask when ordering the concrete. They will be able to give you a good idea of what is needed.
