    Re: Convert Aggregate Base Course from SF to Tons Because it is a foot thick, that''s 12000 ft³ or 444.5 yd³. Weight in tons will depend on the density of the crushed stone used. It can vary. I''m guessing 1.3 - 1.4 US tons per cubic yard, but some materials could be outside that range. Say 600 tons, more or less.
