Approximate volume

4.93 cu yd

High confidence

About 2.03 short tons per cubic yard for normal-weight concrete at roughly 150 lb per cubic foot. The inverse of the volume-to-weight figure. Compare against your compacted or settled requirement rather than the loose delivered figure.

Conversion factor applied
0.49 cu yd per short tons

Working back from a concrete weight to a volume comes up in structural checks: how much a proposed slab adds to a floor, or how much concrete a crane can lift in a skip. The density used is for normal-weight concrete, and lightweight mixes differ considerably, so a structural calculation should use the specified mix density rather than a general figure. Formwork and falsework design in particular is driven by concrete's weight and its fluid pressure while wet, which is a separate and larger consideration than the finished load.

Add the equipment this sizes

This result is a specification — 4.926 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

Why does formwork need to resist so much?
Because wet concrete behaves as a fluid and exerts lateral pressure that increases with pour rate and depth. That pressure, not the finished weight, is what governs formwork and falsework design.
How much can a crane skip hold?
Less than its volume suggests, because concrete is dense. Check the skip's rated capacity in weight against the converted figure rather than filling it to the brim.
Does concrete weight affect the structure below?
It is a primary dead load, and on a suspended slab or an existing floor it is the first thing to check. Adding a screed or topping to an existing floor needs the structure verified rather than assumed.
