How easy was it to use our calculator? Did you face any problem, tell us!

Our 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!

## How Much Gravel Do I Need?

This gravel calculator estimates the volume & weight of gravel needed and here we have manual calculations for both.

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.

### How to 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.

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:

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

### How to Calculate Weight of Gravel:

To calculate the weight needed, using the formula:

$$Density = \frac {mass}{volume} \(mass = Density \times volume$$

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,

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

## What Are The Types of Gravel?

According to their different size & shape, they can be classified into following:

• Bank Gravel
• Bench Gravel
• River Rock (Creek Rock)
• Crushed Stone
• Fine Gravel
• Stone Dust
• Lag Gravel
• Pay Dirt
• Pea Gravel
• Piedmont Gravel
• Plateau Gravel

## How Gravel Calculator Works:

The online gravel estimator allows you to calculate how much gravel you need to convert a rectangular area or circular area, the given steps will help you in using this free online calculator:

Input:

• First of all, choose the area that you need to fill with gravel material, it can either rectangular or circular
• Now, you just have to put the values into the designated field of this online grave calculator
• Tap the calculate button

Output:

The online gravel estimator estimates:

• The volume needed for gravel
• The weight needed for gravel

Note:

It doesn’t matter whether you do gravel calculations for the rectangular or circular area, there you have an option field of price per unit mass. You just have to enter the price/unit of mass into this gravel cost calculator to determine the total cost of gravel you required for your project.
