The **inch**, abbreviated as **in** (or denoted with the symbol **"**) is a unit of length in the British imperial and United States customary systems of measurement.

One inch is to 1/12 of a foot, or 1/36 yard. Since the adoption of the international yard, the yard has been based on the metric system and defined as exactly 25.4 mm.

The **millimetre** (also spelled as **millimeter** in the United States), is a unit of length in the metric system equal to one thousandth of a metre. Therefore, there are one thousand millimetres in a metre.
