Free Gravel Calculator

Gravel Volume Formula:

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

Gravel Volume (cu yd):

1. What is a Free Gravel Calculator?

Definition: This calculator estimates the volume of gravel needed based on project dimensions in feet and inches.

Purpose: It helps homeowners and contractors determine how much gravel is required for driveways, pathways, or construction projects.

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, converted from inches)
27 — Conversion factor (cubic feet per cubic yard)

Explanation: The calculator multiplies length × width × depth (converted to feet) then divides by 27 to convert to cubic yards.

3. Importance of Gravel Volume Calculation

Details: Accurate gravel estimation prevents material shortages, reduces waste, and ensures proper project budgeting.

4. Using the Calculator

Tips: Enter the project area dimensions in feet and depth in inches. All values must be > 0.

5. Frequently Asked Questions (FAQ)

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

Q2: What's a typical gravel depth for driveways?
A: Most driveways use 4-6 inches of gravel, but check local recommendations for your specific project.

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

Q4: Does this include compaction factor?
A: No, for compacted gravel, add 10-20% to the calculated volume.

Q5: How many tons is a cubic yard of gravel?
A: Typically 1.2-1.5 tons depending on gravel type and moisture content.
