Step 3: Convert thickness to meters

In order to calculate the volume of gravel needed in cubic meters, the thickness needs to be converted into meters. This can be done by dividing the thickness in centimeters by 100. For example, if the desired thickness is 5 centimeters, it will be converted to 5/100 = 0.05 meters.

Step 4: Calculate the volume

To calculate the total volume of gravel needed in cubic meters, the area (from step 1) needs to be multiplied by the thickness (converted to meters in step 3). Using the example from step 1 and step 3, the volume can be calculated as follows:

Volume = Area x Thickness

= 50 square meters x 0.05 meters

= 2.5 cubic meters

This means that 2.5 cubic meters of gravel will be needed to cover an area of 50 square meters with a thickness of 5 centimeters.

Step 5: Account for compaction and overfilling

It is important to account for compaction and overfilling when calculating the amount of gravel needed. Compaction refers to the reduction in volume that occurs when the gravel is compressed or settled. Overfilling refers to adding a little extra gravel to ensure that the area is fully covered.

Generally, it is recommended to add 10-15% to the calculated volume to account for compaction and overfilling. In our example, this would mean adding an additional 0.25-0.375 cubic meters of gravel to the calculated volume of 2.5 cubic meters.

In conclusion, calculating the amount of gravel needed in cubic meters involves measuring the area, determining the desired thickness, converting the thickness to meters, and multiplying these values together. It is also important to account for compaction and overfilling in the final calculation.

2. Determine the Desired Depth:

Next, you will need to determine the desired depth of the gravel. This will depend on the purpose of the gravel and the type of project. For example, a 4-inch depth is recommended for a driveway, while a 2-inch depth may be sufficient for a garden path. Once the desired depth is determined, it is important to convert it to feet, as most gravel is sold by the cubic foot.

3. Convert to Cubic Yards:

Most gravel is sold by the cubic yard, so you will need to convert your area measurement in square feet to cubic yards. To do this, simply divide the square footage by 27 (since there are 27 cubic feet in a cubic yard). This will give you the amount of gravel needed in cubic yards.

4. Factor in Compaction:

It is important to consider compaction when estimating the amount of gravel needed. Compaction is the process of compressing the gravel to make it more dense and stable. The amount of compaction will vary depending on the type of gravel and the project, but a general rule of thumb is to add an extra 20-30% to your total calculation.

5. Determine the Weight:

Gravel is sold by weight, so you will need to determine the weight of the gravel needed in tonnes. The weight of gravel can vary depending on its density, which is measured in pounds per cubic foot (pcf). The average density of gravel is approximately 2,835 pounds per cubic yard or 1.42 tonnes per cubic yard. To convert cubic yards to tonnes, simply multiply your total cubic yards by 1.42.
