Calculate the amount of concrete you need for wall, columns, steps and slabs with T-One Building Concrete Calculator!

## Gravel Calculator

### Calculate The Amount Of Gravel You Need For Your Project

T-One Gravel Calculator: Calculate how much gravel you’ll need by entering the desired values into this online calculator (tons and pounds, tonnes and kilograms). Standard pea gravel density is used. Calculating how much gravel is needed to fill an area with a layer of gravel is an issue faced by many builders and gardeners.

The T-One Gravel Calculator is a great help in these situations, but remember that the results are only as good as the measurements and density entered into our gravel calculator. You may also like to take a look at our sand calculator. Brick Calculator. Concrete Calculator. We also have buyer’s guides for river sand and building sand.

Use this online gravel calculator to figure out how many cubic feet, cubic yards, or cubic meters of gravel you will need (tons & pounds, tonnes and kilograms). It has the same density as pea gravel.

#### How to figure out how much gravel you'll need

Many builders and gardeners have to figure out how much gravel they need to fill a certain space or cover a certain area with a gravel layer. In these situations, our gravel calculator is a big help. Keep in mind, though, that the results will only be as good as the measurements and density you put in. Here’s what will happen:

Use geometric formulas, plans, or measurements to figure out how much gravel you will need. Find out or estimate how heavy your favorite gravel mix is. The value set by default is the density of pea gravel.To find the weight, multiply the volume by the density (in the same units). To be safe, it’s usually a good idea to buy 5-6% more gravel than what our calculator says you need.

#### Square or rectangular area

To figure out how much gravel you need to cover a rectangular area, multiply the area by the density of the gravel. As shown in the figure below, the volume formula for a rectangular (or square) box in cubic feet is height(ft) x width(ft) x length(ft)

For 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 = 24ft3 (cubic feet) of gravel and then multiply that number by the density. If you give us the sizes, our pea gravel calculator will do all of this for you.

#### Round area with gravel on it

If you want to cover a round area with gravel or fill a round shape with gravel, the math is a little different: A figure with a round base has a volume that is equal to its height times the area of its base. For the calculator to figure out the area of the foundation, it needs to know its diameter, since the formula is x r2, where r is the radius, or half of the diameter. Again, this will be done for you by the gravel calculator.

#### Area with an odd shape

If the area you’re trying to figure out isn’t a regular shape, things get a little more complicated, but in general, you should divide it into several regular-shaped sections, figure out how much gravel each section needs and how big it is, and then add them all up. Our tool should be useful because it lets you copy with just one click. If you have a lot of sections to add up, you might find our summation calculator helpful.

#### What gravel is and how much of it there is

Gravel is a natural material made up of small pieces of rock carried by water. It can be found in old or new stream beds. Most peas are round and have smooth surfaces, but other characteristics depend on their “parent rock.” You may also come across “crushed gravel,” which is just larger gravel pieces that have been broken down to a smaller size.

Gravel is usually sold with a maximum size guarantee, such as 10mm or 20mm. This means that no side of any particle will be bigger than the size specified. This is done by screening, which is usually done with automated industrial screeners. Keep in mind that this affects how dense the gravel is, so check the manufacturer’s technical specifications for an estimate of the density, which you should then put into our gravel calculator. Gravel usually has a dry density of between 1520 and 1680 kg. If it is mixed with sand, the density is about 1920 kg.

#### Sizes of gravel and crushed stone that are common

In spite of what you might think, there is more than one kind of gravel, each with its own mix of stones and sizes. Choosing the right size and style is important for the success of any building project, since some are more flexible and can be used for different things than others. For example, landscaping gravel would last longer than mulch or pine straw, which makes it great for outdoor spaces that need a durable material. Construction gravel, on the other hand, gives builders and landscapers a solid place to stand. Different kinds of gravel have different densities, and if you know what they are, you can get a better idea of how much gravel you need.

#### Gravel pebbles

The Udden-Wentworth scale divides gravel into two main types: granular gravel and pebble gravel. Pebble gravel can be bought in small bags for small projects, but for bigger ones, you would need to buy it by the cubic meter or by the ton (cubic meter or tonne).
