The next smallest common SI unit is the nanometre, equivalent to one one-thousandth of a micrometre, or one billionth of a metre (0.000000001 m). A micrometer is a unit of Length or Distance in the Metric System. any of various instruments or devices for the accurate measurement of distances or angles. [7] This became necessary because the older usage was incompatible with the official adoption of the unit prefix micro-, denoted μ, during the creation of the SI in 1960. There is another kind of micrometer available called vernier micrometer, which also gives an accuracy of 0.001 mm. An inside micrometer is a device designed to precisely measure things such as the inner diameter of holes. The official symbol for the SI prefix micro- is a Greek lowercase mu.
