If you have crushed stone it's not quite as simple as that. Depending upon the stone size there is a considerable void volume. In smaller crushed stone, say 1 inch size, the volume of the voids is lower (about 25%) than in larger stone where a cubic yard of 6" stone may have a volume of voids of 35%.

Therefore, with a solid stone of granite that has a weight of 165 lbs per cu ft., the voids are equal to about 40 lbs (25% of 165 lbs. fo 1 inch crushed) or the 1 cu ft of 1 inch crushed stone ia about 125 lbs per cubic foot or 27 times that for a cubic yard = 3375 lbs per cu yd. If one then divides by 2000 lbs per ton you get about 1.7 tones per cu yd. of 1 inch crushed granite.

Your best bet is to call a quarry in your local area and ask to speak with a sales representative or someone in quality control.

As far as tons per cubic yards on the #57 Stone; 1.185 tons equals one cubic yard.

Here are some others that may help you...

#4 = 1.110
#5 = 1.092
#57 = 1.185
#67 = 1.164
#89 = 1.188
#9 = 1.273

This is all based on Miami Oolite limestone.

The answer to all your questions is call the quary and ask for the Unit Weight of the product. Once you have the unit weight (lbs/ft3) multiply by the amount of ft^3 you need which is length x width x height and this will tell you how many pounds you need. Then ther are 2000 lbs in a ton so divide by 2000 to get tons. If you know your cubic feet to convert to cubic yards divide by 27 since there are 27ft^3 in a yd^3. Hence 3'x3'x3'=27ft^3. or 1cy

Thumbs up Re: Convert Tons to Cubic Yards

pending on the specific gravity of the asphalt at @ 2.35
1.98 tons of asphalt per cubic yard
so 1 ton = @ 1/2 a cubic yard

Stone density differs from depending on the area, call your quarry where you are getting the rock from and they can tell you the diff. max dry density's for diff stone. In general 57's is 1.9 Ton/CY since it's washed stone.

Ashpalt is 2.14TN/CY so your answer is in Tons divide that by 2.14 and you get CY

Wink Re: Convert Tons to Cubic Yards

I am unregistered, but#6 reply is way wrong. there are 27 cubic ft in a yard,so you would times your 1' square by 27, not 9. the 1.35 is a good compromise for most rock material, I am a general contractor who moves a lot of dirt. thanks
