              Understanding Concrete

              Cubic yards of concrete for a slab. Within construction calculators, concrete belongs to the concrete & masonry cluster, where it shares terminology and assumptions with closely related tools.

              Learning how concrete is calculated

              1 cubic yard = 27 cubic feet. Add 10% for spills. Working through the variables one at a time — — makes the result reproducible by hand and easier to sanity-check.

              Using concrete to make a decision

              Because outputs depend on the assumptions you enter, run more than one scenario before committing to a figure.

              How concrete compares with related measures

              cubic yard, subgrade, cure time, compressive strength all describe adjacent aspects of concrete & masonry. Comparing this calculator's output against those measures — using the related tools listed on this page — prevents a single metric from being read in isolation.
