meq/L

Milliequivalents per liter. An equivalent is a term used in chemistry where the molecular weight of an ion is divided by its charge. The molecular weight of sodium is approximately 23 and the charge on a sodium ion is +1. Dividing the molecular weight by its charge gives an equivalent weight of 23. Calcium has a molecular weight of 40 and has a +2 charge, so the equivalent weight is 20.
