For us Aussies that often buy local Doubler or normal ready-to-use premium eliquid and wish to mix it with our imported nicotine we have in the past had to make the calculation ourselves. Depending on your maths skill this could be ineffective if not dangerous if you get the numbers wrong. I could never find an online calculator for this type of eliquid mixing.
So here is a link to a calculator to help you DIY mix eliquid with nicotine.
