Are you planning to pour a slab to build your terrace or to accommodate an above-ground swimming pool or a jacuzzi? Do you want to determine the volume of concrete needed to carry out your work? For this, you need to know the appropriate mathematical formulas. Do not panic ! Truc Mania teaches you how to master conversions from m² to m³ and vice versa.

## HOW TO DIFFERENTIATE M² FROM M³?

Do you know how to distinguish between square meters and cubic meters  ? It is essential to master these units of measurement before embarking on important works. Thanks to these preliminary calculations, you will save money on your materials, because you will avoid ordering superfluous products. Here are all the secrets to identify m² and m³.

### WHAT ISA M²?

The square meter is a unit of measurement used to express an area . This is essential information to have when doing interior work. Thus, you buy the optimal amount of materials to cover a floor or a wall.

To calculate the area of ​​a rectangular room, simply multiply the length of the room by its width (L x W) . We then obtain the surface in m². If your part is round, apply the following formula: π x r² . In other words, the area of ​​the circle is equal to the radius multiplied by the radius, all multiplied by pi.

### WHAT ISA M³?

The cubic meter is a unit of measurement which makes it possible to express a volume . In the case of the realization of a concrete slab, knowing the volume that it will occupy is essential to order the right quantity of materials.

To calculate the volume of a rectangular solid, we multiply 3 dimensions (length, width and height) according to the following formula: L x W x H . This gives the volume in m³ . If the solid is cylindrical, the expected formula is π x r² xh . In other words, the volume of the cylinder is equal to the radius multiplied by the radius, all multiplied by pi, multiplied by the height (thickness).

## WHAT ARE THE CALCULATIONS TO CONVERT M² TO M³?

Now that you’ve mastered m² and m³, it’s time to learn how to convert these measurements . But before starting your calculations, take care to transpose all your data into the same unit. For example, if your readings are in meters and centimeters, convert them to centimeters only.

### CONVERTM² TO M³

Do you know the surface of your floor? Here is the method to convert m² to m³.

It’s quite simple, just multiply the area by the height of it. For example, if your floor is 4 m long and 2 m wide, multiply these 2 figures and you will obtain the surface in m² (4 x 2 or 8 m²). Suppose you want to pour a slab 10 cm thick, you will need to convert your figures into the same unit of measurement (in centimeters for example), then multiply the surface area by the height and you will obtain the volume of concrete required.

If your floor is triangular in shape , you will need to estimate its area using the following mathematical formula: height x base/2 .

Do you want to pour a round concrete slab to accommodate an above-ground pool? So, determine the area of ​​this circle before calculating the volume of your slab. Here is the formula to follow: 𝜋 x radius² . Once the surface has been obtained, all you have to do is multiply the result by the desired thickness and you will know the volume of concrete to order.

### CONVERTM³ TO M²

If you want to calculate the surface of your slab from its volume, it’s not very complicated. Just divide its volume by its thickness . That’s it !

You now know all the mathematical intricacies to calculate an area and a volume and to convert m² to m³ (and vice versa). You are ready to carry out your work with complete peace of mind.

Be careful, however, to determine the thickness of your slab before you start to ensure the solidity of your work, because a slab that is too thin risks breaking at the slightest shock or in freezing weather. While a slab that is too dense takes a very long time to dry. It is also much more expensive.

As a general rule, the concrete slab should be able to support the weight of your furniture, equipment and people without stress. Thus, if 8 to 10 cm thick is enough to create a landscaped terrace, it will be necessary to design a thicker slab if it is intended for the parking of vehicles or the installation of an above-ground swimming pool.
