How to convert liters to pounds of milk:
(In the U.S., dairy farmers are paid per 100 lb of milk; 1 cwt = 100 lb)
Raw milk doesn't weigh the same as water because of the solids content of milk, so you can't do a straight conversion of mass to volume:
Milk weighs 8.6 lb/gallon (U.S. gallon)
There are 3.7854 liters/U.S. gallon
Therefore: 8.6 lb/ 3.7854 liters = 2.272 lb/liter of milk
Therefore: 100 lb/2.272 lb = 44.01 liters/cwt milk (i.e., there are 44 liters/cwt milk)

If milk price is $25/cwt in the U.S., this converts to a price of US$25/44 = US$.5680/liter
If milk price in $20/cwt in the U.S., this converts to a price of US$20/44 = US$.4544/liter
If milk price is $17/cwt in the U.S., this converts to a price of US$17/44 = US$.3862/liter
If milk price in $15/cwt in the U.S., this converts to a price of US$15/44 = US$.3408/liter
If milk price in $12/cwt in the U.S., this converts to a price of US$12/44 = US$.2726/liter
(i.e., divide US$/cwt by 44 to get US$/liter)

If milk price is $.60/liter, this converts to a price of $26.41/cwt in the U.S.
If milk price is $.50/liter, this converts to a price of $22.00/cwt in the U.S.
If milk price is $.40/liter, this converts to a price of $17.61/cwt in the U.S.
If milk price is $.30/liter, this converts to a price of $13.20/cwt in the U.S.
If milk price is $.25/liter, this converts to a price of $11.00/cwt in the U.S.
(i.e., multiply US$/liter by 44 to get US$/cwt)
