How much unflavored do you have? What is the nic content? If you have 30ml of unflavored eliquid you don't have enough to make 100ml.
Also, unless you're making 300ml of juice, you will not use all of the flavoring. Depending on the flavoring you have, you will only use 10-20% flavoring in your juice.
So, a little more info is needed to properly answer your question.
The calculator I use is here: ejuice me up
Well heres a second option for the calculator. e-Liquid Calculator
It looks like you may be missing something . Theres no total liquid amount given for you 60/40 mix nor wether or not theres any nicotine involved. Is your 60/40 already mixed to the strength you would like?
All-in-all, counting the amount of flavoring you have, you should be able to make a total of 132ml of juice, up to 150ml if you use all of the flavoring. A word of caution about that though - you don't want to start with more than 10% flavor. You can adjust upward if you need to. If you use too much flavoring the juice will NOT taste good, and you can't take the flavoring out!
Check this thread in the DIY E-Liquid section: http://www.e-cigarette-forum.com/forum/diy-e-liquid/74109-guide-diy-flavoring.html. There's lots of info there for the beginner DIYer. I picked up a lot from there to help me out. Just out of curiosity, what flavor did you get in a 30ml bottle?
And now you can post in that forum as well if you have any additional questions.![]()
