Micrometre - Wikipedia The micrometre (micrometer in US spelling; symbol: μm) is a unit of length in the International System of Units (SI) equalling 10−6 metre (SI standard prefix "micro-" = 10−6); that is, one millionth of a metre (or one thousandth of a millimetre, 0 001 mm, or about 0 000 04 inch) It is also known as the micron [1]
Micrometers - Starrett In the hands of a skilled operator, the precision micrometer is the most accurate hand-held tool available When close measurements are necessary, the micrometer is the ideal tool for the job because measurement and reading are on the same axis and the anvil end is supported by a strong frame
