it depends on what your measuring if you want mass use grams if you want weight use Newtons or pounds if you want vollume use liters or pints ect. but for what i think your doing you would use either milliliters or centameters
Metres
Potatoes are sold by the kilogram.
To measure the mm of an item you would need to use a metric ruler. The metric ruler has cm and mm on it.
You would measure that in grams, or milligrams.
centimeter
its liters
Pints
Milliliters (mL)
Milliliters/mL (Metric) or Fluid Ounces/Fl Oz (Imperial)
The volume of the bottle would be in litres.
Of course, how else would you measure how much milk you'd have? You could measure in Imperial gallons, but the metric Litre (or Liter) is also a common way to measure liquid substance (which what milk is, a liquid).
Liquid is often measured in a tall glass cylinder that has a graduated scale etched on its surface.
You would use a millilitre or, equivalently, a cubic centimetre. A larger unit, which could be used, is a litre.
The metric volume of a sink would be measured in litres.
That would depend on what liquid you where measuring. gallons are a measure of volume, whereas a tonne is a measure of mass. One tonne is one thousand kilograms.

That would be the liter.
