pro tips

914.4 mm is exactly one yard; half a yard is 457.2 mm.
For precision work, keep the .4 — it's 0.4 mm per yard and it adds up.
what it does
One yard is 914.4 millimeters. Multiply yards by 914.4 and the millimeters appear, which is how a fabric order in yards becomes a metric cut a machine understands.
It shows up when a pattern in millimeters has to be cut from a bolt sold by the yard, when a DIY plan in yards has to be drilled at millimetre precision, when trim or tubing is ordered in yards but fitted in millimeters, and in any project that crosses the two systems.
The shortcut: 1 yard is about 914 mm, so 2 yards is 1,829 mm, half a yard is 457 mm, and a quarter yard is 229 mm. Rounding to 914 is fine for cloth and wrong for anything that has to seal.
