View Full Version : Sqaure footage to tons

How would I go about converting total square footage to tons? I have 1640 sq. ft. of surface area at a 2" depth that I want to pave in asphalt. I would like to know how much asphalt I need in tons. Thanks!

To determine the volume, multiply the area in sqaure feet by the depth in feet.
1640 square foot * (2 inches / 12) foot = 273.33 cubic foot
Now the tough part. To convert volume to weight, you need to know the density. I found data that crushed asphalt has a density of 45 pounds/cubic foot. This may not be the correct data for the type of asphalt you are using, if not the result will not be correct.
273.33 cubic foot * 45 pounds/cubic foot = 12299.85 pounds
12299.85 pounds / 2000 = 6.15 tons

There is a relatively simple way based on the construction business. Take you sf (1640) divided by 162 (2" depth coverage) this will give you 10.13 cubic yards. You then multiply this by 1.4 (weight ratio) to get 14.19 tons.
