1 picogram
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
2 µm bacterium
A 2 µm long illustrative bacterium. Species and growth conditions vary.
An illustrative mass chosen for this teaching specimen, stored independently from its size. Actual composition, hydration and specimen dimensions vary.
Defined examples — our methodology
The marked mass is calibrated. Unmeasured illustration details are representative.

- Comparing
- Mass ↔ Mass
- 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.
