The vital body substances are measured in terms of equivalents. When the amount of substance in equivalents has very small size, the term milliequivalents is used. It is expressed in terms of meq or mEq. 1 equivalent = 1000 milliequivalents. In terms of grams the equivalent weight is equal to 1000 milliequivalent weights. This unit is mostly used for the measurement of compounds in biological fluids such as potassium in the blood. Listed below are several commonly used electrolytes and their milliequivalent weights.
