Hi all:

The new 4 L jugs of milk we buy at COSTCO here Maryland saves space compared 
with the current gallon jug.

The 4 L jug has a perimeter of 5 cm less than the gallon jug.  Both are the 
same height. 

This is another example of improved efficiency which can be achieved by 
converting to the SI.

Regards,  Stan Doore
