1 nanometre
From Wikipedia, the free encyclopedia
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
Distances longer than 10 nanometres
