The term mg is the common abbreviation of millegram (1,000th of a gram). The term or abbreviation meq (often expressed as mEq) is used in chemistry, Biology and atomic measurements to express an infinitesimally small amount of a substance refered to as an equivalent (not pronounced like the word meaning "to be the same as or similar to" somthing; rather the "a" in . . ."valent" has the long "a" sound ( ā ) as in the words pay or hay. I would suggest that you do a search for eqivalent as used in the abovementioned sciences for a more complete explanation. Cosmicstargate

Milligrams (mg) measure the weight or mass of a substance, while milliequivalents (mEq) measure the concentration of ions in a solution that can participate in a chemical reaction. The mEq value takes into account the valence of the ion being measured, providing a more accurate representation of its activity in a solution compared to just the weight measurement in mg.
