Concrete Calculator

How to accurately calculate the concrete you will need for your project

Use the volume calculations below for each of the shapes you are using on your site. You can build up a concrete calculation for complicated areas by adding additional shapes of each type.

Please note when calculating concrete you can only use one unit denomination of inches, feet, millimetres, centimetres or metres. The same measurement must be used for length, width and depth.

VOLUME = WIDTH x LENGTH x HEIGHT

ENTERING MEASUREMENTS

We know measurements can be a real hassle when laying concrete and if not done correctly, the results can be far from what you expected. For example, you cannot mix units of measurement…

When using feet to enter dimensions you must enter 0.5 feet for 6 inches

If you simply enter 6, this will calculate 6 feet not 6 inches.

We realise this can be confusing, so to help you convert inches for depth into feet please see the information below. It is important that you insert the decimal when entering the measurement e.g. 0.17 not 17.

INCH TO FEET CONVERSION TABLE

1 inch = 0.09 feet 4 inch = 0.34 feet 7 inch = 0.59 feet 10 inch = 0.84 feet
2 inch = 0.17 feet 5 inch = 0.42 feet 8 inch = 0.67 feet 11 inch = 0.92 feet
3 inch = 0.25 feet 6 inch = 0.5 feet 9 inch = 0.75 feet

This same principle applies when dealing in metric. If you enter your first two measurements, (for example, 5 metres x 3 metres) and your depth is 6 inches or 150mm, you would enter this as 5m x 4m x 0.150 = 2.3 cubic metres.
