What these units are
Yards (yd). A yard is exactly 0.9144 meters, or 3 feet. It is the unit for fabric and carpet sales, and for sports distances such as the 22-yard cricket pitch.
Millimeters (mm). A millimeter is one thousandth of a meter. It is the unit for precision work — engineering tolerances, rainfall, wire gauges and the thickness of paper or sheet metal.
Metric-to-metric conversions are exact. Imperial figures are exact by definition but are rounded for display, so a value converted back and forth can differ in the final digit.
Converting Yards to Millimeters in practice
Working in yards
The yard is exactly 0.9144 meters, three feet or thirty-six inches. It is a defined multiple of the meter, not an independent standard. Its value was fixed by the same international agreement that defined the foot and the inch.
Fabric, carpet and some flooring are still sold by the yard, and the chain and furlong used in land and horse racing are built from yards. American football is measured in yards.
Conversions run through the exact metric value, so a yard in meters is exactly 0.9144 and in centimeters exactly 91.44. Printed results are rounded, which can alter the final digit on a conversion there and back.
A yard is not a meter, though the two are close enough that a rough estimate will look plausible on fabric. Buyers who order yards and measure in meters can come up short.
A yard is three feet, a little less than a meter. Fabric is sold in yards in some markets and in meters in others, so a price per yard and a price per meter are not comparable, differing by about nine percent.
Checking a yards to millimeters conversion
Inside the metric units every length conversion is a shift of the decimal point, so millimeters to centimeters, meters to kilometers and the rest can be done by moving it. Which way, and how far, follows from the prefix alone.
Converting between metric and imperial is not a shift but a single exact multiplication, and the factor is the same one for that pair however large or small the value. The trap is mixing the two systems halfway, as when a distance is stated in meters and inches in the same sentence.
To check a length conversion, run it backwards, or convert through a familiar middle value such as a meter or a foot. The one thing to keep straight is pairs that differ by a thousand rather than by ten, since those are where a misplaced decimal point survives unnoticed.
