Comment on Anon helps with his gf's vaping addiction

Let’s say it’s 50mg/30ml. To get to 49mg/30ml you need 49/50 of the original bottle or 29.4ml of the original concentration with the last bit being 0 nic.
Now our hypothetical 50% nic bottle has 15ml nicotine. 49% would be 14.7ml. Now our original mix is 50%, so we have to add twice as much as that 14.7ml to get to 49%. 14.7×2= … 29.4ml.
The cool thing about dimensional analysis is that once you cancel out your dimensions the math takes care of itself, same as if you’re using percentages. Anon may not know much about vape juice, but his math is on point.

I’m not trying to be rude here, but the math is not my problem, I understand dimensional analysis.
After doing that calculation, is it likely that you are going to mistake the term “percent” and “mg”, or after doing something so specific with units are you more likely to use the right one?
I’m saying that if OP actually did any of this (you say their math is on point but they didn’t do any haha) they’d probably be using the correct term rather than the incorrect yet common “street” term

The point of my math is that it doesn’t matter if it’s mg or percent. Assuming the bottles remain consistent, the difference for each step will be the same volume.
