Weight to Volume Material Calculator

Find how many cubic yards of gravel, sand, topsoil, or mulch a target delivery weight (in tons) will give you.

Computed in your browser — nothing you enter is uploaded. Figures are presented for United States against IRC 2024, and every formula is cited under regulatory standards below.

Estimated volume

7.41 cubic yards

Check your inputs

Actual density varies with moisture content and compaction — a supplier's actual yield per ton may differ somewhat from this average-density estimate.

Weight
20000 lb

Running these inputs gives 7.41 cubic yards as the estimated volume. Note that weight sits at the low end of the range this calculator was checked against, so treat the output as indicative rather than settled. Expect some drift against the real job; the calculation is solid but conditions on site are not. Currently reading for United States under IRC 2024 — pick a different market above and the figures re-cast accordingly.

Estimated cost — your price

This site holds no price list for this material — local prices vary too much to publish honestly. Enter your supplier's price and the result is costed with it.

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. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

Frequently asked questions

When would I know weight but not volume?
Many bulk material suppliers price and deliver by the ton rather than the cubic yard, especially for dense materials like gravel and sand — this helps translate a ton-based quote back into the volume you actually need to plan coverage.
Should I round up when ordering?
Since suppliers typically sell by weight in fixed truck-load increments anyway, use this mainly to sanity-check that an ordered weight will cover your planned area — cross-check with a coverage calculator like Gravel Driveway or Topsoil for the area-based requirement.
Does this match the Material Volume to Weight Calculator exactly in reverse?
Yes — the two calculators use the same density assumptions and are mathematical inverses of each other, so a value converted one way and back gives the original number.
