You need the charge of the ion to convert equivalents to moles, and you need the molar mass to convert to grams.

This matches the information I found at the RxList.com website for Micro-K® time release potassium chloride:

"Micro-K (potassium chloride extended-release) ® Extencaps® capsules and Micro-K (potassium chloride extended-release) ® 10 Extencaps® capsules are oral dosage forms of microencapsulated potassium chloride containing 600 and 750 mg, respectively, of potassium chloride USP equivalent to 8 and 10 mEq of potassium."

I also discovered the mEq is "molar equivalent" rather than "medical equivalent", which makes the general concept easier to understand, which is fabulous . . .

Fabulous!

Note 1: mEq is "milli equivalent", which is one thousandth of an equivalent. An "equivalent" can be the same as a mole, but it does depend on the nature of what is being examined. For potassium (K) 1 equivalent = 1 mole.

Note 2: the website mentioned above: http://www.rxlist.com/micro-k-drug.htm

On what basis for equivalence since potassium gluconate ISN'T potassium chloride?

Re: mEq to mg conversion

Perhaps what someone needs to know here is that MOLES are like PAIRS or DOZENS. There are 2 like items in a pair (of shoes, e.g.); 12 like items in a dozen (eggs, e.g.) and 6.022 X 10^23 like items in a mole (of atoms or molecules, e.g.).

Trying to convert a milliequivalent of potassium gluconate into milligrams of potassium chloride "doesn't compute". It's like subtracting five shoes and a banana from ten pairs of shoes.

It is easy enough to convert a milliequivalent of potassium chloride (which K-lyte is) to milligrams of potassium chloride (of, say, another brand). However, it is IMPOSSIBLE to convert a milliequivalent of potassium chloride to milligrams of an UNKNOWN potassium salt.

Re: mEq to mg conversion

74.5 mg of Potassium Chloride = 1 mmol or 1mEq of Potassium
Got this information from my hospital pharmacy manual !

Re: mEq to mg conversion

For those of you asking on this thread for medical reasons, I would recommend (as a doctor):
a) ask the manufacturer directly: how many mEq per dose (tablet/capsule/whatever) in this particular product, and then
b) discuss directly with your doctor - I'd like to switch from X to Y and I've found out this information about dosing. Is this safe?

....all BEFORE switching.
