    Since gr iss=100mg, I presume the answer is 200mg.

    This question brings back memories. In my second semester of nursing school I was about to give my first injection, which made me nervous enough. Then I saw that the physician had written the order in grains. Fortunately I had brought my conversion table along.

    If my memory serves me right (and its been a long time since I did anything with grains). You are converting 2.5 grains to mg. 1 grain = 64.8 mg, so if I am correct the answer should be 162mg

    griiss = 150 mg (2.5 gr x 60 mg/gr = 150 mg) -hth!
    i =1 and ss= 1/2 so it is 2.5 gr (I had to take latin in hs)

    ii = 2, ss = 1/2 so you would have 2 1/2 grains

    There are 65 mg per gr so you would have 162.5 mg in (iiss grains).

    At least this is the way I figured it!

    I always remember that a plain, regular aspirin is 5 gr/325mg. Roughly 1 gr/65 mg. Therefore iiss (2 l/2) gr / 162.5 mg

    But who is still using grains? Shouldn't all those old docs have died (or at least retired) by now????

    Interesting some say 65 and some say 60 mg per grain. Last semester when we went over this we were told 60grains per mg.

    JC does not like to see "iss" and similar entries in charts because it leads to ----guess what!! Confusion and possible med errors. I will be glad when grain orders are extinct.

    I always remeber that 10 grains of Aspirin = 650 mg, hence 1 grain = 65 mg, or else I've got years of incident reports to catch up on.

    Unit conversion dot org says 10 grains = 647.989100002 milligrams.

    I was taught 60 mg to 1 grain. This is interesting...

    Seriously, is anybody still ordering in grains? In all my years of nursing I have never once seen an order using the apothecary system. Nursing students have enough to worry about without cramming useless information into their poor brains.
