Help please

If it's this one - https://www.vampirevape.co.uk/watermelon-flavour-concentrate-30ml

It says this in the details



So if you want to mix at 15%, use what I posted.

You didn't say how much juice you wanted to make, so I am just giving you quantities to make 100ml. You'll have to adjust accordingly. The percentages I gave you are correct, for 18mg 50/50 with 15% concentrate.

Thanks mate I really appreciate your help

I've shown the steam engine mix calculator to be inaccurate.
Iirc think it was the weight discrepancies but it was so long ago that it may have been corrected by now.

Well by volume it gives exactly the same result as @hack400 gave above, Never used weight myself.
