An online gravel calculator helps to estimate how much gravel in volume and weight you need to complete your earthwork project. However, by using this online gravel cost calculator you come to know how much the gravel material will cost you!

Well, if you are going to improve the beauty of your surface area with pea gravel materials, this gravel or aggregate calculator is the right choice to do so. Now, give a try to this free gravel estimator will that tells you how much stone, rock, gravel or material of your choice you need to complete your project.

It doesn’t matter whether you want to know how much stone, rock, or gravel material you need to complete the project, “this gravel quantity calculator will calculate the precise measurements for the material of your choice”.

## How Much Gravel Do I Need?

This online gravel calculator estimates the volume & weight of gravel needed and here we have manual calculations for both. Let’s begin!

And, if you concerned to determine how much mulch you need for a given area at a specified depth, then this online mulch calculator works best for you.

### Calculate Volume of Gravel:

To calculate the volume needed, follow the given steps:

•  Measure the length & width of the area for which you going for the construction.
•  Find out the area of the surface from length & width. $$(A = L \times W)$$.
•  Determine the depth of the surface.
•  Find out the volume by multiplying the area and depth.
•  The volume obtained is the volume needed for the gravel to complete the project.

Let’s have an example:

Example:

A surface has $$18 ft$$ long and $$21 ft$$ wide with a depth of $$10 ft$$. Then how much gravel do I need?

Solution:

$$L = 18 ft$$
$$W = 21 ft$$
$$D = 10 ft$$
So, find the area by,
$$A = L \times W$$
$$A = 18 \times 21$$
$$A = 378 ft^2$$
Now,

Calculate the volume by using the formula:

$$V = A \times D$$
$$V = 378 \times 10$$
$$V = 3780 ft^3$$

### Calculate Weight of Gravel:

To calculate the weight needed, using the formula:

$$Density = \frac {mass}{volume} \(mass = Density \times volume$$
You don’t have to remember the density; our gravel calculator sets this value by default.

Let’s try an example:

Example:

If the volume needed is $$3780 ft^3$$ and the density is $$104.88 lb/ft^3$$, then find the weight needed?

Solution:

Here,

$$Density = 104.88 lb/ft^3$$
$$Volume = 3780 ft^3$$
So,

$$mass = Density \times volume$$
$$mass = 104.88 \times 3780$$
$$mass = 396446.4 lbs (198.223 tons)$$

## How Much Does Pea Gravel Cost?

### What is gravel used for?

It mixed with asphalt for road construction as well as mixing with and for the manufacturing of concrete. Its common use is to surface the roadways especially icy roads.

### Does crushed gravel drain well?

Yes, the crushed gravel drains well and is great in paving the blocks and in concrete for footpaths. So, if you have an area where water doesn’t drain, then add some crushed stone which is helpful for draining and for decorating feature.

## Wrapping-it Up:

In large projects, a miscalculation does happening too much, so even using this driveway gravel calculator, it is important to consult to professional. Now, it becomes to manage your road construction projects with the assistance of this free online gravel estimator.
