How do you convert milliequivalent to percentage?

Answer 1

This depends on what you would like to use the value for. If analysing a soil sample, it would be best to report the value per 100g of soil as this is the current convention.

So,

meq% = (meq/ 100 g soil) x 100

Answer 2

To convert milliequivalents (mEq) to a percentage, you need to know the molecular weight of the substance. Divide the milliequivalents by the molecular weight to get the number of moles. Then, convert moles to grams by multiplying by the molecular weight. Finally, divide the weight in grams by the total weight of the solution and multiply by 100 to get the percentage.
