Mass
In your hand
Bar length measures mass, not physical size. Both bars start at zero kilograms (kg). Pictures identify the objects only.
A little perspective
100 micrograms is about 1.67 times the mass of a salt crystal.

Mass: 60 µg; defined specimen.
A chosen 0.3 mm table-salt crystal. The irregular illustration is a scale specimen.
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.

The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
Mass is distinct from weight: an object’s mass stays the same as gravity changes.
