Yards to inches (yd to in)

One yard is exactly 36 inches: three feet of twelve. The yard is the unit the 1959 international agreement actually defined, at exactly 0.9144 meters, and the inch is a thirty-sixth of it.

Worked through: 1 yd x 36 = 36 in.

Going the other way, one inch is 0.0277777778 yards.

For mental arithmetic: Multiply by 36: multiply by 3 for feet, then by 12.

Fabric, almost entirely, and fabric is cut in eighths of a yard, so the useful table is the fractions rather than the factor: an eighth is 4.5 inches, a quarter 9, a third 12, a half 18, five eighths 22.5, three quarters 27. Quilters have their own unit built on this. A fat quarter is a half yard cut in half across the bolt, roughly 18 by 21 or 22 inches. It is the same area as a quarter-yard cut straight across at 9 inches by the full width, but a far more useful shape, which is why fabric shops sell it pre-cut.

Precision is worth matching to the input. A measurement given as 0.125 yd carries one or two significant figures, and reporting its conversion to six implies a precision the original never had.
