10 pLVolume

Too small to see at this scale. The ring marks its true-scale position, not its volume. The shape has not been enlarged.

0.05 ml drop

A drop is a very small portion of liquid formed by surface tension.

50 µLVolume
These are equal-volume cubes. Edge lengths grow with the cube root of capacity; the cubes do not depict container exteriors.

A little perspective

The capacity of a 0.05 ml drop is about 5,000,000 times 10 picolitres.

How to read the visual

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

  • The volume of a 0.05 ml drop: This is an illustrative comparison value, not a claim that every example is the same.

Volume measures three-dimensional space; a container’s capacity is not its outside dimensions.
