    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

    :)

    i used to use it when i bought juice, coz a vendor would be out of stock of e.g. 18mg (i like 18mg most)...but they only had 24mg and they had 12 or 6mg..then i could work out what to do. how much to moer into what bottle.:)

    doing the sums with a pencil is all rambo, but my head starts hurting...then found that spreadsheet and now i cheat everytime:)

    So I have a tricky one, how can I turn your 36mg nic into 100mg nic:p.

    Ok but seriously, I make self mix for me and the immediate family. I done it the first time 2 weeks ago and hell it was tons of shaking! My wrist is still sore!
    I would like to make the flavouring bulk and then add higher strength nic so I don't mess the flavour ratio up due to the 50% nic quantity I need for 18mg and 25% for 9mg etc.

    I am asking if you can do stronger nic please? Or if anyone has an idea that does not include the manual shaking or magnetic stirrers. For the time being I have had to say to them 'Sorry you have to buy pre made next time'.

    Regards,
    Fickie

    Dunno about other vendors, but we are not prepared to sell anything higher than 3.6mg (3.6% Vol). Higher than 36 you start running the risk of getting seriously ill even if it just touches your skin - we might be over protective here, but I'd rather err on the side of caution

    As for mixing - you can make yourself a magnetic stirrer from some old PC fans and an old PC power supply, all you would need to buy are the little magnetic modules used for stirring and they are not that expensive

    Just google DIY magnetic stirrer - there are plenty around as beer brewers have been DIY-ing them for years

    You can check your answers in eJuice Me Up, there's a built in nic blending calculator that pops up when you click the X3 button.

    @Derick this is a great peace of information, I talk to a lot of people that want to change the nic strength of a juice they enjoy, and this will be useful resource to calculate how much is need to change nic level in a juice.

    Thank you Great find.

    ok just a quick question regarding upping nic
    Correct me where im wrong

    This Is wat I did
    Had 5ml 9mg vm4
    Added 0.5ml 36mg vg
    Thinking im making 12 mg

    Reason being 36mg stands for 36mg/ml
    So 0.1ml should be 3.6mg
    And I added 0.5 to the 5ml@ 9mg
    Thinking 0.1 for every ml will add 3.6mg to every ml
    Making 12ml

    5mlx9mg =45mg total
    Add 0.5 x36=18 mg bringing total nic to 63mg รท5.5ml giving me 11.45mg
    Close to 12 mg

    @mbera, my JuiceCalculator says 0.625 ml of 36 mg would have been what you should have added. So, close enough.

    @Hash Punk If you add 10ml 36mg Nic to 20ml of a PG/VG Mixture you will have 30ml of 12mg.

    You would need to add 10ml of 36mg nicotine, so you will arrive at 30ml total juice at 12mg nic content.
