How to Calculate Tonnage Conversions for Crushed Materials (e.g., 1.78 Cubic Yards to Tons)?

Time: 6 March 2021

To convert cubic yards to tons for crushed materials (e.g., gravel, sand, limestone), you’ll need to take into account the material’s density, typically measured in pounds per cubic yard. Follow these steps:

1. Find the Density of the Material

Determine the approximate density of the crushed material. Here are common densities for reference:

• Gravel: ~2,400 lbs per cubic yard
• Limestone: ~2,600 lbs per cubic yard
• Sand: ~2,700 lbs per cubic yard

If you’re uncertain, check with the supplier or consult standard density values for the material you are working with.

2. Convert Cubic Yards to Pounds

For the given cubic yard quantity, multiply by the density:\[\text{Weight (lbs)} = \text{Cubic yards} \times \text{Density (lbs per cubic yard)}\]

Example: If the material has a density of 2,600 lbs per cubic yard and you are converting 1.78 cubic yards:\[1.78 \, \text{cubic yards} \times 2,600 \, \text{lbs per cubic yard} = 4,628 \, \text{lbs}\]

3. Convert Pounds to Tons

Since 1 ton equals 2,000 pounds, divide the weight in pounds by 2,000 to get tons:\[\text{Weight (tons)} = \frac{\text{Weight (lbs)}}{2,000}\]

Using the example above:\[4,628 \, \text{lbs} \div 2,000 = 2.31 \, \text{tons}\]

Final Answer for 1.78 Cubic Yards:

• If the material density is 2,600 lbs/cubic yard, 1.78 cubic yards equals approximately 2.31 tons.

Note: Always double-check the density of your specific material as variations can affect the result.
