So we had this question from a customer and after some google-fu we finally found the answer and I decided to share.
What if you have some 6mg base and 36mg base and you want to increase the 6mg to 12mg, how much 36mg do you need to add to your 6mg to get it to 12mg
Here's a handy formula worked out by people smarter than me
Vd = ( Vo * ( Sf - So ) ) / ( Sd - Sf )
Vo = Volume Original (ml)
So = Strength Original (mg/ml)
Vd = Volume Delta (how much base you add) (ml)
Sd = Strength of Delta (how strong is the base you're adding) (mg/ml)
Sf = Strength Final (mg/ml)
So lets say that you just have 10ml for now then the values are as below
Vo = 10ml
So = 6mg
Sd = 36mg
Sf = 12mg
Vd = (Vo * (Sf- So))/(Sd - Sf)
vd = (10 * (12 - 6))/(36 - 12)
vd = (10 * 6) / 24
VD = 60/24
VD = 2.5ml
So you need to add 2.5ml of 36mg base to a 6mg base to make it 12mg
