- Comparing
- Length ↔ Characteristic size
- Relative size
- Salt crystal is larger on this measurement by a factor of about 1.2. Salt crystal's selected measurement is approximately 20% greater than 250 micrometres's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Salt crystal is labelled representative; treat the displayed value as a comparison anchor rather than false precision.
