About These Calculators
Every stone project is won or lost on two numbers: the volume of the space you are filling and the weight of the material that fills it. Angular crushed aggregates such as ASTM C33 #57 stone (about 2,500 lbs per cubic yard, or 1.25 US tons) interlock under compaction to form structural driveway bases, shed pads, and slab sub-bases, while washed round stone and pea gravel (roughly 2,600 lbs per cubic yard) keep void space open for French drains and drainage trenches. Sands and crusher run sit in between, packing tighter as their fine particles fill the gaps. Because compacted stone shrinks 10% to 15% from its loose dumped volume, every calculator in this silo applies a compaction buffer automatically and reports your order three ways at once: cubic yards for the quarry, US tons for the delivery truck's legal payload, and 50 lb bag counts for small weekend jobs—plus the exact yardage where bulk delivery starts beating bags on price.
