https://www.vetnurse.co.uk/f/nonclinical-discussions/12944/calculations Hi there, I&#39;ve been doing some revision lately on calculations and have found conflicting formulae on sites and in books. I was just wondering which formula you guys use to change ml to mg in drug calculations? Thanks :) en-USTelligent Community 10https://www.vetnurse.co.uk/thread/111211?ContentTypeID=1Sun, 27 Mar 2011 19:35:44 GMT1a0763ec-3885-442c-853e-6cef656dfec5:8cbdd0d3-3bb1-49b7-9fe5-02bc5f13acebxhappysvn21x<p>what kind of calculation are you doing. give us an example it may be easier to explain</p><div style="clear:both;"></div>https://www.vetnurse.co.uk/thread/110672?ContentTypeID=1Sun, 20 Mar 2011 10:57:35 GMT1a0763ec-3885-442c-853e-6cef656dfec5:438fbcfa-fe8c-460b-ac74-9de45a74be49Geniverger<p>I&#39;m not exactly sure what you mean but I think to convert a dose in ml to mg you need to multiply the dose in ml by the mg/ml given on the bottle, vial or data sheet which will give you the total dose in mg. You would need to work out the patients&#39;s dose in mg first anyway though to get the dose in ml by working out weight x mg/kg.</p><div style="clear:both;"></div>
