In the United States, water used for irrigation is measured in acre-feet. An acre-foot of water covers an acre to a depth of exactly 1 foot. An acre is 4840 yd^2.
If desalinated water costs $1950 per acre-foot, how much does desalinated water cost per liter?

Convert 4840 square yards to square feet and that to cm^2. Convert 1 foot to cm. Calculate volume in cc and that will be in liters. The cost will be $1950/??liters. Convert to 1L.
