Material Weight Calculator

Convert a volume of bulk material into weight using published densities — for delivery limits, skip loading and floor capacity.

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.

Check your inputs

Typical dry loose densities. Moisture and compaction move real figures by 10-25%, so treat a result near a load limit as needing a weighbridge rather than a table.

Metric tonnes
1.76 tons
US short tons

Pounds

Density used
99.88 pcf

Running these inputs gives 1600 kg as the weight. Note that volume 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.

Regulatory standards & verification citations

  • Bulk densities: FHWA and state DOT aggregate handbooks; ACI 211 for normal-weight concrete at 2400 kg/m³
  • Loose bulk densities vary with moisture content and compaction — figures here are typical dry loose values

Frequently asked questions

Why does the same material have different weights?
Moisture and compaction. Wet sand carries water in every void, and a compacted stone base has fewer voids than the same stone tipped loose. The swing between dry loose and wet compacted is routinely 25%, which is the difference between a legal load and an overweight one.
Which ton — metric or short?
Both are shown. A metric tonne is 1000 kg; a US short ton is 907 kg, about 10% lighter. Skip and truck limits are quoted in whichever the country uses, and confusing them is a 10% error in the direction that gets you turned away at the gate.
Can I use this for a floor loading check?
For the weight, yes. For whether the floor takes it, no — that depends on the structure, the span, how the load is distributed and what else is on the floor. A pile of material on a suspended slab is a point load question for an engineer, not an arithmetic one.
Why is mulch so much lighter than soil?
It is mostly air and organic fibre rather than mineral particles. Bark mulch runs around 400 kg/m³ against topsoil's 1300, so a truck that carries three cubic metres of soil will carry far more mulch by volume before it reaches its weight limit.
