Calcium can be measured by the amount of the calcium salt (mg of the cation plus the anion, or mL of a specified concentration) or the amount of elemental calcium in milligrams (mg), in milliequivalents (mEq), or in millimoles (mmol). (Because calcium has a valence of +2, the milliequivalents equals two times the number of millimoles.) Its varied dosing units and conversion factors are potential sources of medication errors.
Enter a value in a cell and click the Calculate button in the same row to determine all the equivalent forms. Be aware that there may be some rounding error with multiple conversions.
