Chickpea

Defined dry-seed mass: 300 mg; defined specimen; range 200 mg–500 mg.

A defined dry chickpea 9 mm across and 300 mg in mass. Cultivar, grading and moisture change both values.

Defined examples — our methodology

The marked defined dry-seed 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.

  • We use 300 mg for the dry-seed mass of a chickpea; the recorded range is 200 mg–500 mg.
  • The dry-seed mass of a chickpea: 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.
