ran across this web site during my travels through the internet tonight. you might want to bookmark it. by inputing any measurement next to it's label, the conversion machine will return to you the conversion of that number in a score of different measurements. i think many of you doing pharmacology questions are going to find this resource invaluable if you are having trouble with conversions. http://www.convert-me.com/en/ - convert me.com. you can get your answers to all kinds of measurement conversions at this site! it is a conversion machine. you can convert weight and mass (great for nursing pharmacology!!!!) and temperature (for nursing), plus many other categories. bookmark this one! clicking on the various units of measurement themselves will take you to a page with a table of standard conversions for those who want to work the conversions on their own. the links to get into the conversion machines is down at the middle section of the opening page.
