20mm Shingle Calculator

20mm Shingle Volume Formula:

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

Shingle Volume (cu yd):

1. What is a 20mm Shingle Calculator?

Definition: This calculator estimates the volume of 20mm shingle needed based on the area dimensions and desired depth.

Purpose: It helps construction professionals and DIYers determine how much shingle is required for landscaping and 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 shingle (cubic yards)
\( L \) — Length (feet)
\( W \) — Width (feet)
\( D \) — Depth (feet)
27 — Conversion factor (cubic feet per cubic yard)

Explanation: The length, width and depth are multiplied to get cubic feet, then divided by 27 to convert to cubic yards.

3. Importance of Shingle Volume Calculation

Details: Proper shingle volume estimation ensures adequate coverage, proper drainage, and cost-effective material purchasing.

4. Using the Calculator

Tips: Enter the length and width in feet, and the desired depth in feet (typically 0.25-0.5 ft for most applications). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is 20mm shingle used for?
A: 20mm shingle is commonly used for driveways, paths, drainage systems, and decorative landscaping.

Q2: How deep should I lay shingle?
A: Typically 3-6 inches (0.25-0.5 feet) for most applications, but may vary based on specific project requirements.

Q3: Does this include compaction?
A: No, consider adding 10-20% to the calculated volume to account for compaction.

Q4: Can I use this for other aggregate sizes?
A: Yes, the calculation works for any aggregate size, though compaction factors may vary.

Q5: How many tons is a cubic yard of 20mm shingle?
A: Approximately 1.3-1.5 tons per cubic yard, depending on material density and moisture content.
