This is not mine I brought this over from Mass Monsters and it was originally posted by Superchicken. I found it helpful when I started doing my own conversions and figured it would be useful to those who were unfamiliar with conversions.
Generally 1 gram of powder/hormone will displace .75ml of volume when dissolved in a liquid. however this varies a bit but usually is not significant. eq comes to mind as well which is .85ml per gram.
to find out how to make a certain mg/ml concentration you need to do a few things:
lets say we want 300mg/ml and want 100ml total. and lets assume that 5%ba will keep this in solution.
obviously we will need the final volume to be 100ml
100ml x300mg in each ml
100x300=30,000mg total hormone used
1000mg=1g
30,000mg=30g
since 1g=.75ml then 30g=22.5ml
so now we want 100ml and know we need to add 30g hormone to achieve 300mg/ml. since 30g=22.5ml, we now have 77.5ml left to displace with something else.
now we need to add enough ba to achieve 5% of the total volume.
100ml x .05(.05=5%) =5ml ba
so we had 100ml total and subtracted 22.5ml to make room for the hormone, then subtract another 5ml to make room for the ba, which leaves us with 72.5ml. this is how much oil or pg etc... we will need to add.
to get to 100 total ml we use 30g hormone which is equall to 22.5ml
add 5ml ba
add 72.5ml oil
22.5+5+72.5=100
now everyone should be able to figure out how to make any mg/ml in any total amount of ml. if you still dont understand how to make 200mg/ml with 50ml total, or 150mg/ml in 75ml total, well god help you, you should give up
also keep in mind that an average 25mm sterile filter will keep about 1.5ml of oil in it. so for certain conversion methods you may need to compensate for this by adding an extra 1.5ml of oil. but not all methods of conversion will need to compensate. just wanted to bring that to everyones attention because for most people it will make a difference.
