Question

If you need to measure the volume of liquid in a bottle of eyedrops, what unit would be the most practical?

Answer 1

Surely, `"millilitres"`, `1` `mL` `=` `10^-3mL`

Explanation:

An eye dropper probably delivers a `0.1*mL` volume drop by drop. How would you design an experiment that would test this measurement?

On the other hand, a Pasteur pipette, a much finer glass filament, delivers a volume of approx. `0.01*mL` per drop.
