Everyday area conversions

Volume and material ordering

Concrete, mulch and gravel are sold by volume, and trim and flooring by the running foot — neither is an area conversion, and both are here because people look for them as if they were.

• Cubic feet to cubic yards

  1 cu ft = 0.037037 cu yd

• Linear feet to square feet

  Needs a width as well as a length — the page explains why, and asks for it.

Working the other way

A converter takes an area you already have. If you still need to measure one, the square footage calculator turns width and length into an area and shows it in four units at once, and the shape calculators cover the circles, triangles and L-shaped rooms a plain rectangle cannot. For a whole property, the multi-room total adds every space into one figure.
