Concrete Slab Volume Calculator (Metric Units)

Concrete Calculator For Slabs The Concrete Slab Volume Calculator - Metric computes the exact amount of ready-mix needed for rectangular floor slabs, patios, and driveways. Enter slab length and width in metres plus thickness in millimetres; the tool instantly returns:
  • Area in square metres, functional for finish material estimates.
  • Concrete volume in cubic metres (primary ordering unit).
  • Parallel figures in cubic yards and cubic feet for suppliers who quote in imperial

Calculator

  1. enter the length measurement of the slab in metres
  2. the width of the slab in metres
  3. thickness of the slab in millimetres

Results

  1. the area of the slab in square metres
  2. amount of concrete needed in cubic metres
  3. concrete needed in cubic yards
  4. concrete needed in cubic feet

Formula's used:

length * width * depth = V

Example calculation: 
slab length = 10 m
width = 8 m
concrete slab thickness = 100 mm --- changing mm to m 100 ÷ 1000  = 0.1
10 * 8 * 0.1 = 8
You will need 8 cubic metres of concrete for this slab

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. It is recommended, depending on the job you are doing, to add anywhere from an extra 4% to 10% to your concrete order 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.
