Nanometer is a length unit used to express distance, size or travel range in practical measurement work.
The prefix nano- (one billionth, from Greek nanos, dwarf) was adopted with the SI in 1960; the nanometer is the usual unit for light wavelengths and semiconductor feature sizes.
Measurement system: Metric, imperial and internationally standardized length usage. SI equivalent: 1 nm = 1.000000e-9 m.
