Come on you guys.
What do you need a calculator for..
Just say you are going to make 100ml's
All you need to know are 3 things.
1. BA = 2% or .02 x 100ml = 2mls
2. BB = 18% or .18 x 100ml = 18mls
3. G of powder if you making 10ml vials at 300mg/ml each vial will contain 3g of powder, 100ml makes 10 vials and 10vials x 3g = 30g of powder
Once you have all this in your beaker bring up the heat to 120'f it should be clear and all powder suspended
Then just all enough oil to fill beaker to 100ml.
Reheat up to 120-140 for 20 min
Then reduce heat to 100-110 and filter.
You don't need a calculator infact relying on a calculator is going cause problems.
