The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 10−2 metres ( 1 100 m = 0.01 m). To help compare different orders of magnitude, this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm). 1 cm – 10 millimetres. 1 cm – 0.39 inches. 1 cm – edge of a square of area 1 cm 2.
Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property ...

Original nominal 25 mm figure scale; though a 6-foot human in 1:87 is closer to 21 mm. 1:82: 3.717 mm An intermediate scale (HO/OO) intended to apply to both HO and OO scale train sets.
The microwave is between 1 meter to 1 millimeter. The millimetre (international spelling; SI unit symbol mm) or millimeter (American spelling) is a unit of length in the International System of Units (SI), equal to one thousandth of a metre, which is the SI base unit of length. Therefore, there are one thousand millimetres in a metre.
Metric equivalents are approximate, converted at 1 pes = 296 mm. Other units of area described by Columella in his De Re Rustica include the porca of 180 × 30 Roman feet (about 473 m 2 or 5,090 sq ft) used in Hispania Baetica and the Gallic candetum or cadetum of 100 feet [ clarification needed ] in the city or 150 in the country.

The informal public imperial measurement standards erected at the Royal Observatory, Greenwich, London, in the 19th century: 1 British yard, 2 feet, 1 foot, 6 inches, and 3 inches. The inexact monument was designed to permit rods of the correct measure to fit snugly into its pins at an ambient temperature of 62 °F (16.66 °C).
