Bar length measures mass, not physical size.

A little perspective

The mass of 10 micrograms and the defined wet mass of Copepod are approximately the same.

Measurements, assumptions & sources +

10 micrograms

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

NIST — SI conversion factors

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 wet mass is calibrated. Unmeasured illustration details are representative.

Why these numbers?

The visual compares mass with defined wet mass. The records below preserve each value’s basis and caveats.

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.

Comparing: Mass ↔ Defined wet mass
Relative size: The two selected measurements are approximately equal.

How to read the visual

The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.

Copepod uses a 10 µg central value within a recorded range of 3 µg–30 µg.
Copepod is labelled defined specimen; treat the displayed value as a comparison anchor rather than false precision.
The recorded ranges overlap, so the ordering can vary even though the central values differ.
