Fill Sand Tons to Cubic Yards Calculator

Convert a fill sand tonnage into cubic yards to check coverage, capacity and storage.

Approximate volume

7.69 cu yd

High confidence

About 1.3 short tons per cubic yard for fill sand; coarser and less uniform than bedding sand. The inverse of the volume-to-weight figure. Compare against the compacted or settled requirement, not the loose delivered figure.

Conversion factor applied
0.77 cu yd per short tons

Converting a fill sand tonnage into volume tells you how much backfill a load provides. The figure to hold in mind is that compaction takes a meaningful fraction of it: sand placed in layers and vibrated occupies less space than the loose delivered material, and backfill that is not compacted settles later, taking whatever is above it down as well. Trench reinstatement failures are frequently a compaction problem rather than a material one.

Add the equipment this sizes

This result is a specification — 7.692 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 fill my trench?
Convert to volume, then add for compaction. Backfill placed loose and left to settle produces the depressions you see over old trenches; compacting in layers avoids them and consumes more material.
Why does backfill settle?
Because loose material densifies over time under its own weight and traffic. Compacting during placement does that work up front instead of leaving it to happen under a finished surface.
Can I use site-won material instead?
Sometimes, if it is suitable and free of organics and oversized stone. Clay-rich spoil compacts poorly and holds water, which is why imported sand is often specified even where excavated material is available.
