Eaches is a quantity of measurement equal to what?

Eaches is the plural form of each and is often used to denote a number of individual items taken from a larger package.

For example:

There may be 20 cases on one pallet

There may be 10 eaches in one case

So in the above example 1 pallet would be equal to 200 eaches.

Note that the measurement 'each' is entirely dependent on packaging and usage.

The term "Eaches" is often synonymous with "Pieces".
