Is it all right if we tell you to consume the water at an average rate of 23 microliters per second (23 �L/s)? Even though this isn't realistic as a set of instructions, it illustrates the concept of normalization, where the denominator in the expression is unity (i.e., 1 of something, requiring only the unit's symbol). There's a very common exception -- L/100 km. (Price/100 g is not, of course, an exception, as currency units are not SI.) Bill Potts, CMS Roseville, CA http://metric1.org [SI Navigator]
