How many mEq in a mmolL in lactate?

To convert millimoles per liter (mmol/L) of lactate to milliequivalents per liter (mEq/L), you need to consider the charge of the lactate ion. Lactate (C3H5O3^-) has one negative charge, so 1 mmol/L of lactate is equivalent to 1 mEq/L. Therefore, the conversion is straightforward: 1 mmol/L of lactate equals 1 mEq/L of lactate.
