Conversion Calculator

 

To calculate the quantity needed for a particular job, measure the length, width, thickness and product density (located below), of the area, plug in your numbers and our aggregate calculator will estimate the amount you will need to order.

Please make sure to add 10% more to your total quantity to take into account waste during product placement.

Instructions: If you do not know the actual density, select the type of geology and product from the lists below and hit the “Estimate Density” button. An estimated density factor should then appear in the above density field.

NOTE: A number of factors can influence the exact quantities needed for your particular job. You are encouraged to work with a local Vulcan Sales Representative for more exact product estimates. To identify the sales representative in your area, use our Facility Finder.

Manual Calculator

 

  1. Multiply the length of the area by the width of the area = Square Feet
  2. Multiply Square Feet by the Depth* = Cubic Feet
  3. Divide Cubic Feet by 27 = Cubic Yards
  4. Multiply Cubic Yards by 1.5 = Tons Needed
For figuring round areas, use the following example:

24 ft round pool – 4″ deep

Start with 1/2 the radius:
12 x 12 = 144
144 x (3.14) x depth divided by 27 x unit weight

Example:
12 x 12 = 144
x 3.14 = 452.16
x .33 = 149.21
÷ 27 = 5.53
x 1.5 = 8.30 tons
