Concrete: convert m2 to m3

For your home, you need to pour a concrete slab? Concern: you have your measurements in square meters and you need to know how much concrete you will need in cubic meters. We explain very simply how to move from square meter to cubic meter for calculating the volume of your concrete slab.

Calculation concrete slab: find the right volume

The calculation for a concrete slab and, in particular, the conversion from square meter to cubic meter for volume, is a frequently asked question. Whether to make your terrace, for a simple slab, for a plinth of garden shed or for a small driveway, this calculation is necessary in order to determine the right amounts of concrete needed.

This amount will then give you the exact proportions of cement, sand, water and gravel to use for your concrete. As in the kitchen, the more your concrete will be made with the exact quantities, the more likely it is to hold in time. That is why the correctness of the calculation of your slab is necessary.

Concrete: a must-have material

As we know, concrete is a valuable ally throughout the building sector. In addition to base cement, water, sand and gravel, additives can be used for desired effects: texture, colour, surfacing, etc.

Concrete has recognized properties: strength, longevity, resistance to pressure and compression, temperature, fire, water … There is not only one type of concrete. Various concretes have been developed to succeed in making progressively more and better than just foundations. Increasingly technical and tall buildings have emerged thanks to the evolution of concrete. Today, a formwork for concrete slab seems very simple compared to the very beginnings of concrete.

Conversion square meter — cubic meter

Don’t panic, even if you’re one of the people who have never been really strong at math. The formula is simpler than you think, to convert one square meter into a cubic meter. You should know that your concrete slab must have the right proportions (cement, sand, water, gravel).

The basic measurements for the slab , expressed in square metres, must also be accurate and rechecked before any conversion and before the final calculation in cubic metres. First of all, it will be necessary to differentiate the span tile from the slab laid on the floor. Similarly, consider differentiating the inner slab from the outer tile, which will not require the same preparations.

Slab thickness: convert with the right volumes

To convert one square meter to cubic meter, it is necessary first of all to determine a perimeter, and a concrete slab thickness . Your two-dimensional concrete slab must therefore be made into a three-dimensional slab.

Calculation of the area of the slab (square meter): length x width

Calculation of the volume of the slab (cubic meter): length x width x thickness

Practical example : your concrete deck slab should be 6 meters by 5. Its area will therefore be 30 square meters. If you want to give it a thickness of 15 centimeters, it will also be necessary to convert centimeters into meters. The volume of your concrete slab will be:

30 m² x 0.15 cm = 4.5 cubic meters

Doing this simple calculation then allows you to make the calculation of the price that will cost you your volume of concrete , gravel, sand and cement (in bag). For all your work, the calculation square meter/cubic meter is essential, whether you are a simple Sunday handyman or a building professional.

How to calculate the area of your tile to put a coating?

Your slab is now cast. Whether it is intended for your terrace, garage or inside your home if you are doing renovation, it is not meant to remain raw. Currently, you can choose several coatings depending on the room, such as:

  • tiling
  • real parquet
  • the laminate
  • the composite
  • the lino

Of course for the interior of your home, apart from the tile, you will have to put an insulator just above the tile. Again you can choose to put a simple thermal insulator or add an acoustic insulation if you are upstairs. Whatever you choose, it remains for you to know how much materials you will have to plan. Inevitably you will ask yourself this question: How to calculate the area of a room? If the answer is relatively simple to find for a square or rectangular room, it can quickly become more complex, if you are facing an atypical room. It is better to ensure the shot, by clicking on the link. This will save you from finding yourself with fewer flooring blades or packs of tiles to bring back to your supplier, if your supplier accepts them.
