Does one ferrous sulfate 5 gr tablet equal one 325 mg tablet?

Answer 1

To get from grains to milligrams you'll need a conversion factor like 1 gr = 64.8 mg. 5 gr x 64.8 mg = 324 mg, so you decide that's close enough and give 1 tab. 1 gr Rounding to 60 mg/1 gr, as is often done, gives 300 mg as your answer, which might cause you to doubt if you will be giving the ordered dose. 3. You just opened a 500 mL bottle of guaifenesin and will be giving 1 tablespoon per dose. How many doses are in the bottle? In other words how many tablespoons are in 500 mL? 500 mL x 1 tsp x 1 tbs = 33 tbs 4.93 mL 3 tsp Rounding to 5 mL gives you the same answer, so rounding to 5 mL is reasonable.
