2mm
Grain of rice
2mm is two millimeters—a unit of length equal to two thousandths of a meter, or about the thickness of a nickel.
The measurement appears in technical specifications, craft supplies, and product descriptions: 2mm lead for mechanical pencils, 2mm neoprene wetsuit.
In ammunition, it would designate an unusually small caliber.
