About the yard and the millimeter
The yard
The yard (yd) is a unit of length in the imperial and US customary systems, defined as exactly 0.9144 meters (3 feet). It is used in American football field measurements, fabric and textile retail, and many landscaping contexts. The international yard was harmonized with the imperial yard in 1959.
The millimeter
The millimeter (mm) is a metric unit of length equal to one-thousandth of a meter. It is the working unit of engineering drawings, precision manufacturing, electronics, and most consumer-goods specifications outside the United States. A credit card is about 0.76 mm thick; the diameter of a pencil lead is around 2 mm.
