    Since the industry went belly up the site where I purchased my e juice from is no longer offering my juice or DYI supplies

    SO I'm trying to figure out how to make my own.

    I purchased 36mg nicotine in 100%PG
    I purchased both VG and PG and some flavorings

    I like a 50/50 mix on the PG/VG with a target of 24mg and sometimes 18mg nic

    Its very confusing trying to calc 36mg nicotine @ 100%PG into a 50/50 mix with a target of 24mg nic (and sometimes 18mg) ,

    I don't know how to enter the proper %'s in the fields and for some reason I cant get any calculator to stop giving me negative number errors with either the VG or the PG

    Any suggestions?
    If I can just see how to do it once, I should be OK afterwards

    Um, half of 36mg/ml is 18mg/ml, so a 50/50 mix is only possible if you make 18 mg/ml with no flavor. (flavorings are usually PG just like your 36mg/ml nic)

    I would recommend getting at least 100mg nic juice, that way you can play with 50/50 VG/PG without neg numbers.

    Thanks for the reply
    Ive been away for a while since I asked the question.

    I should have got the 100mg (next time) but I have a bottle of 36mg nic in 100%pg

    I want to make a 50/50 mix (with a nic range of approx 18 to 24mg)
    Do I just cut the bottle of nic in half (at whatever size that bottle is) and add 50%VG to it to get 18mg?

    For example
    If was to make a 30ml bottle, what I'm not sure of is how much nic @ 36mg 100% PG I would need to add to the 30ml bottle to get the nic to a strength range of approx 18 to 24mg

    That's what the calc is made for ya' know :)

    You fill the bottle half up i.e. 15ml of 36mg pg. If you add 15ml 0mg VG, so the bottle is full now, then you have a 18mg 50/50 PG/VG mixture. You've essentially diluted your nic by cutting it in half hence half strength.

    How am I supposed to use this? Its just a .xls file. Where is the calculator with all the options and inventory stuff at?

    It's a DIY-calc spreadsheet in XLS format, meaning to be opened/used from an XLS reader, like e.g. MS-excel, open/libre-office or online from google-docs etc.

    Extremely helpful. I’m brand new at mixing. I think I’m putting too much flavor in, since most of the recipes appear to be 10.00 and I’m using 16.00 which has been a tad too much on the mixes I’ve done the last 2 Days. I was basically copying off of another recipe.

    Quick question, 1ml of water is 1 gram, how do I measure juice? Just wondering since most everyone on this forum, that I have seen, agrees that weight is easier than volume.

    Again, thank you for the spreadsheet. It will be a huge help.

    Hi mate,
    I use the values below:

    PG: 1.038 grams per ml (I round to 1.0)
    VG: 1.26 grams per ml

    Pure Nicotine: 1.01 grams per ml
    100mg in PG base: 1.0352 grams per ml
    100mg in VG base: 1.235 grams per ml

    For PG based flavour: 1.0 grams per ml
    Have fun
    I

    One last question, what percent of flavor do you use? I’m aware that it will vary depending on the flavor and probably the brand, but I have been using 16% as a general rule. Is this too much, not enough, a good starting point?
