I have an area that is 210' in length, 85' in width. I want to install a 6" base using crushed stone. I know I would use the following to obtain Cubic Yards: length x width x depth, divided by 27 to obtain cubic yards. I need to convert to tons. Need help! Thanks!

Please send a formula to convert to tons. If I need weight where could I go to obtain a weight chart for aggregates. Thanks!
