    The nanometre (SI symbol: nm) is a unit of length in the metric system equal to 10 −9 metres (⁠ 1 / 1 000 000 000 ⁠ m = 0. 000 000 001 m). To help compare different orders of magnitude , this section lists lengths between 10 −9 and 10 −8 m (1 nm and 10 nm).

    In SI writing style, this may be written 40 Mm (40 megametres). An inch is defined as exactly 25.4 mm . Using scientific notation, this value can be uniformly expressed to any desired precision, from the nearest tenth of a millimeter 2.54 × 10 1 mm to the nearest nanometer 2.540 0000 × 10 1 mm , or beyond.
