Both marked spans share one linear scale. Artwork keeps its proportions; poses and surface detail are illustrative.

A little perspective

The length of 100 micrometres and the thickness of Sheet of paper are approximately the same.

Measurements, assumptions & sources +

100 micrometres

The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.

NIST — SI conversion factors

Sheet of paper

A 0.1 mm thick sheet. Paper stock and compression change thickness.

Defined examples — our methodology

The marked thickness is calibrated. Unmeasured illustration details are representative.

Length ↔ Thickness
Relative size
The two selected measurements are approximately equal.

How to read the visual

The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.

  • Sheet of paper is labelled example; treat the displayed value as a comparison anchor rather than false precision.
