Ernie gave you the math formula to find the amount of pergolide mesylate you need in order to have 1mg of the active ingredient (pergolide).
The only time this will really be an issue is if you are switching from Prascend to a compounded version. The easiest way to do it is to tell the pharmacy you want to provide the equivalent of however many mgs of Prascend you need. For example, if you are giving 3mg Prascend then tell the pharmacy you want the compounded to be of equal strength to 3mg of Prascend. They will do the math and send the correct compounded strength to you.
Hash tagged threads (for those like me who are clueless about this stuff) are the "colored highlight" at the end of the topic name - in this case, this post is: Switching from Prascend to Pergolide Mesylate dosage, then #pergolidestrength colored in green. Click on that colored portion and it will take you to a list of posts all dealing with the strength of pergolide.
