You may also encounter "crushed gravel", which is simply larger gravel particles crushed to a smaller desired size. The peas are usually rounded with smooth surfaces, while other properties depend on "parent rock". Gravel is a naturally occurring material, consisting of water-born pieces of rock and is found in buried or current stream beds. In case you end up with a large number of sections to sum, you might appreciate our summation calculator. The one-click copy function of our tool should come in handy. In case the area you are calculating has an irregular shape, things get a bit more difficult, but in general what you would want to do is divide it in several regularly-shaped sections, calculate their volume and gravel requirements and then sum them up together. Again, the gravel calculator will do this math for you. To calculate the foundation area the calculator needs its diameter, since the formula is π x r 2, where r is the radius, or diameter/2. The volume of a figure with a round foundation is its height times the area of its foundation. If the area you want to cover with gravel, or the shape you want to fill is round, the calculation is a bit different: Our pea gravel calculator handles all this for you given you supply the dimensions. The volume formula for a rectangular (or square) box in cubic feet is height(ft) x width(ft) x length(ft), as seen in the figure below:įor example, to fill a box with a width of 3ft and a length of 6ft, to a depth of 1ft, you need to multiply 1ft x 3ft x 6ft = 24ft 3 (cubic feet) of gravel, then multiply that by the density. To calculate how much gravel you need to cover a rectangular area you need to multiply the volume by the gravel density. It is often a good idea to consider buying 5-6% more gravel than estimated by our calculator, to be on the safe side. Multiply the volume by the density (in the same units) to get the weight.Estimate or learn the density of your preferred gravel mix.Estimate the volume of gravel needed, using geometrical formulas and plans or measurements.Our gravel calculator is a great assistance in such cases, keeping in mind that the results will only be as good as the entered measurements and density. Many builders and gardeners face the task of calculating or estimating the amount of gravel they would need to fill a given space or cover a given area with a layer of gravel. How much does a cubic meter of gravel weigh?.The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies.
