Gravel Calculator

Gravel Volume Formula:

\[ V = \frac{L \times W \times D}{27} \]

Gravel Volume (cu yd):

1. What is a Gravel Calculator?

Definition: This calculator estimates the volume of gravel needed based on the area dimensions and desired depth.

Purpose: It helps construction professionals and DIYers determine how much gravel is required for projects like driveways, walkways, or foundations.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \frac{L \times W \times D}{27} \]

Where:

\( V \) — Volume of gravel (cubic yards)
\( L \) — Length (feet)
\( W \) — Width (feet)
\( D \) — Depth (feet)
27 — Conversion factor (cubic feet per cubic yard)

Explanation: The calculator first converts depth from inches to feet, then multiplies length × width × depth, and divides by 27 to convert to cubic yards.

3. Importance of Gravel Volume Calculation

Details: Proper gravel volume estimation ensures proper project planning, accurate material ordering, and cost control.

4. Using the Calculator

Tips: Measure the area's length and width in feet, and enter the desired depth in inches. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 27?
A: There are 27 cubic feet in 1 cubic yard, so we divide by 27 to convert the volume from cubic feet to cubic yards.

Q2: What's a typical gravel depth?
A: For driveways, 4-6 inches is common. For walkways, 2-3 inches. Adjust based on your project needs.

Q3: How do I measure irregular areas?
A: Break the area into rectangular sections, calculate each separately, then sum the volumes.

Q4: Does this include compaction?
A: No, consider adding 10-20% extra for compaction depending on material type.

Q5: How many tons is a cubic yard?
A: Typically 1.2-1.4 tons per cubic yard, but varies by material density.
