In liters or _cubic_ meters

Any unit of measurement is fine if it can be easily converted into metrics :)

Depends first on the cow breed, then on the system used by the farmer, then by the cow's genes.
On average, the black and white Holstein-Friesian produces ~7,200litres/year in Europe, but in North America produces ~10,000litres/year (difference is due to hormones which are used in the USA but banned in Europe). Strangely enough, both have a lifetime's yield of around 30,000 litres.
Other breeds give less (eg. Jersey gives ~5,000 litres/year)

Milk production is always measured in pound of milk and not in gallon or liters
