Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative.
A little perspective
The length of 5 ångströms is about 1.79 times the characteristic size of Water molecule.

Water molecule
A chosen 0.28 nm molecular-scale model. Effective molecular size depends on the definition.
University of Utah — Cell size and scale
The marked characteristic size is calibrated. Unmeasured illustration details are representative.

Why these numbers?
The visual compares length with characteristic size. The records below preserve each value’s basis and caveats.

- Comparing
- Length ↔ Characteristic size
- Relative size
- 5 ångströms is larger on this measurement by a factor of about 1.79. 5 ångströms's selected measurement is approximately 78.6% greater than Water molecule's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Water molecule is labelled representative; treat the displayed value as a comparison anchor rather than false precision.
