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

A little perspective

50 milligrams is about 1.25 times the dry-seed mass of a lentil.

Measurements, assumptions & sources +

50 milligrams

Mass: 50 mg; definition.

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

NIST — SI conversion factors

Lentil

Defined dry-seed mass: 40 mg; defined specimen; range 30 mg–50 mg.

A defined dry lentil seed 5 mm across and 40 mg in mass. Cultivar, moisture and grading change size and mass; the seed is lens-shaped rather than spherical.

Defined examples — our methodology

The marked defined dry-seed mass is calibrated. Unmeasured illustration details are representative.

Relative size
50 milligrams is about 1.25 times the dry-seed mass of a lentil. 50 milligrams is approximately 25% greater than the dry-seed mass of a lentil.

How to read the visual

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

  • We use 40 mg for the dry-seed mass of a lentil; the recorded range is 30 mg–50 mg.
  • The dry-seed mass of a lentil: This is an illustrative comparison value, not a claim that every example is the same.
  • The recorded ranges overlap, so the ordering can vary even though the central values differ.

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