Units & Standards

What Is a Yard and What Is a Millimeter?

The yard (yd) is an imperial and US customary unit of length equal to 3 feet or 36 inches. It is standardized internationally as exactly 0.9144 meters.

The millimeter (mm) is the International System of Units (SI) metric standard for precision linear measurement, defined as one-thousandth of a meter (0.001 m) or one-tenth of a centimeter.

Because each inch equals exactly 25.4 millimeters and 1 yard contains 36 inches: 1 yard = 36 × 25.4 mm = exactly 914.4 millimeters.
