Bar length measures mass, not physical size. Both bars start at zero kilograms (kg). Pictures identify the objects only.

A little perspective

The mass of a yeast cell is about 4 times 10 picograms.

Measurements, assumptions & sources +

10 picograms

Mass: 10 pg; definition.

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

NIST — SI conversion factors

Yeast cell

Mass: 40 pg; defined specimen.

A chosen 5 µm yeast cell; species and growth stage alter its size.

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.

How to read the visual

The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.

  • Yeast cell: An illustrative mass chosen for this teaching specimen, stored independently from its size. Actual composition, hydration and specimen dimensions vary.

Mass is distinct from weight: an object’s mass stays the same as gravity changes.
