20mm Gravel Calculator Yards

20mm Gravel Volume Formula:

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

Gravel Volume (cu yd):

1. What is a 20mm Gravel Calculator?

Definition: This calculator estimates the volume of 20mm gravel needed based on length, width, and depth measurements.

Purpose: It helps determine how much 20mm gravel is required for landscaping, construction, or drainage 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)
27 — Conversion factor (cubic feet per cubic yard)

Explanation: The calculator converts the cubic feet measurement to cubic yards by dividing by 27.

3. Importance of 20mm Gravel Calculation

Details: Proper gravel volume estimation ensures you purchase the right amount of material, avoiding project delays or excess costs.

4. Using the Calculator

Tips: Enter the length, width, and depth in feet. All values must be > 0. For irregular areas, divide into rectangular sections.

5. Frequently Asked Questions (FAQ)

Q1: What is 20mm gravel used for?
A: 20mm gravel is commonly used for drainage systems, driveways, pathways, and as a base for concrete slabs.

Q2: How do I measure depth for gravel?
A: Measure the desired depth after compaction. For most applications, 2-4 inches (0.17-0.33 feet) is typical.

Q3: Should I account for compaction?
A: Yes, gravel compacts about 15-20%. Consider ordering 10-15% more than calculated.

Q4: How many tons is a cubic yard of 20mm gravel?
A: Approximately 1.4 tons per cubic yard, but this varies by material density.

Q5: Can I use this for other gravel sizes?
A: Yes, the formula works for any gravel size, but compaction rates may vary.
