1. What is #57 Stone?

#57 stone is a specific size of crushed stone (about 3/4" to 1" in diameter) commonly used for drainage, driveways, and concrete mixes. It's named for its size classification in the ASTM standard.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( Tons \) — Weight in US tons (2000 pounds)
• \( Density \) — Material density in tons per cubic yard (typically 1.4-1.6 for #57 stone)

Explanation: The formula converts weight (tons) to volume (cubic yards) using the material's density.

3. Importance of Density

Details: Density varies based on stone type, moisture content, and compaction. The default value of 1.5 tons/cu yd is typical for #57 stone but may need adjustment for specific materials.

4. Using the Calculator

Tips: Enter the weight in tons and the material density. For #57 stone, density typically ranges from 1.4 to 1.6 tons per cubic yard.

5. Frequently Asked Questions (FAQ)

Q1: Why convert tons to cubic yards?
A: Construction materials are often sold by weight (tons) but needed by volume (cubic yards) for project planning.

Q2: What's the density range for #57 stone?
A: Typically 1.4-1.6 tons per cubic yard, depending on composition and moisture content.

Q3: How much does a cubic yard of #57 stone weigh?
A: Approximately 1.5 tons (3000 pounds) at typical density.

Q4: How accurate is this conversion?
A: Accuracy depends on knowing the exact density of your material. When in doubt, consult your supplier.

Q5: Can this be used for other materials?
A: Yes, but you must use the correct density for each specific material type.
