Scale illustration of Quinoa seed, calibrated to its defined seed diameter measurement.
The marked defined seed diameter represents 2 mm.

A little perspective

About the same scale as Copepod.

Copepod: A copepod is a tiny aquatic crustacean found in marine and freshwater environments, playing a key role in aquatic food webs.

Measurements, assumptions & sources +

Quinoa seed

A defined dry quinoa seed 2 mm across and 3 mg in mass. Variety, moisture and seed grading affect both values.

Defined examples — our methodology

The marked defined seed diameter is calibrated. Unmeasured illustration details are representative.

Copepod

A defined 2 mm adult calanoid copepod specimen with a 10 microgram wet mass. The body span excludes the long antennules; species, life stage and hydration produce wide variation.

Defined examples — our methodology

The marked defined body length is calibrated. Unmeasured illustration details are representative.

Why this measurement?

Why we use 2 mm

For comparison, this page uses defined seed diameter. This is labelled defined specimen: an explicit comparison model rather than a claim that every example has the same value. The recorded range is 1.7 mm to 2.3 mm.

A defined dry quinoa seed 2 mm across and 3 mg in mass. Variety, moisture and seed grading affect both values.

The marked horizontal span follows the named feature; transparent margins and unmeasured details do not alter it. How calibrated comparisons work →
