Approximate volume

7.41 cu yd

High confidence

About 1.35 short tons per cubic yard for dense-graded crushed limestone; dust content and gradation shift this either way. The inverse of the volume-to-weight figure. Compare against your compacted or settled requirement rather than the loose delivered figure.

Conversion factor applied
0.74 cu yd per short tons

Checking whether a quoted limestone tonnage will build the sub-base you have designed means converting to volume and then comparing against the compacted requirement rather than the loose one. Dense-graded limestone is engineered to lock together under compaction, so the finished layer occupies less space than the delivered pile. The other variable worth asking about is fines content: a material with more dust compacts tighter and weighs more per yard than a cleaner, more open grading, so two quotes for nominally the same product can differ in what they actually deliver.

Add the equipment this sizes

This result is a specification — 7.407 cu yd — not a quantity. Put the thing it sizes into your project: how many, what you call it, and your supplier’s price.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.

Frequently asked questions

Will this tonnage make my sub-base?
Convert to volume, divide by the area, and compare the result against the compacted thickness specified — then add for the volume lost to compaction. The loose figure alone will overstate what you finish with.
Does dust content change the value?
It changes the density and the behaviour. More fines means more weight per yard and tighter compaction; a cleaner grading is more free-draining but locks together less. Neither is universally better, so match it to the application.
Can I use limestone under paving?
It is common practice for sub-base, with a separate bedding layer above. Limestone is not a bedding material — it needs the correct sand or grit above it depending on the paving system.
