1 nanometre

To help compare different orders of magnitudes this page lists lengths between 10⁻⁹ metres and 10⁻⁸ metres (1 nanometre and 10 nanometres).

Distances shorter than 1 nanometre

• 1 nm = 1 nanometre = 1000 picometres = 10 angstroms
• 2 nm – diameter of DNA helix^[1]
• 3.4 nm – length of a DNA turn (10 bp)^[2]
• 3.48 nm – size of an albumin protein molecule^[3]
• 5 nm – size of the gate length of a 16 nm processor.
• 6.8 nm – width of a haemoglobin molecule^[4]
• 7.5 nm – thickness of a cell membrane
