    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 cm10 millimeters; 1 cm – 0.39 inches; 1 cm – edge of a square of area 1 cm 2

    en.wikipedia.org/wiki/Millimetre

    Therefore, there are one thousand millimetres in a metre. There are ten millimetres in a centimetre. One millimetre is equal to 1000 micrometres or 1 000 000 nanometres. Since an inch is officially defined as exactly 25.4 millimetres, a millimetre is equal to exactly 5 ⁄ 127 (≈ 0.03937) of an inch.

  8. Micrometer (device) - Wikipedia

    It is often covered by insulating plastic plates which further reduce heat transference. Explanation: if one holds the frame long enough so that it heats up by 10 °C, then the increase in length of any 10 cm linear piece of steel is of magnitude 1/100 mm. For micrometers this is their typical accuracy range.
