Frequently Asked Questions
Common questions about the free online gravel calculator.
Use the prism formula, volume = area x depth. Multiply the length by the width, then multiply
by the gravel depth in feet.
Multiply the volume in cubic yards by the density in tons per cubic yard. Crushed stone is
usually about 1.4 tons per cubic yard.
A driveway base is normally 4 inches (10 cm) of compacted crushed stone, laid in two layers
of 2 inches for better compaction.
Crushed stone is about 1.4 tons per cubic yard, pea gravel about 1.35, and sand about 1.3.
Check with your supplier for an exact figure.
It depends on the stone. Most crushed gravel weighs between 1.35 and 1.45 tons per cubic yard
once it is compacted in place.
A path usually needs 2 inches (5 cm) of gravel over a weed membrane, which is about 0.06
cubic yards for every 10 square feet.
Yes, order about 10 percent more than the calculation because gravel spreads, compacts, and
some is lost into the subgrade.
A US short ton is 2000 pounds, or 0.907 metric tonnes, while a metric tonne is 1000
kilograms, so the figures differ by 9 percent.
Yes. Choose metres and centimetres and the tool converts everything to feet internally before
returning cubic yards and tons.
