Calculating Dilution?

[EmeraldLeo1982]

So I made 4 bottles of 5ml single flavor juices to get a baseline strength for each flavor. Some need 5-10% more flavoring, and I think they could all use a lil VG as 2 or 3 hits makes my throat/lungs feel like they've been punched and are inflammed temporarily.

Using math how do I calculate the dilution of adding VG and flavoring. I have an ejuice calculator app but it doesn't do reverse calculations.

So for example..

I have 5ml 24mg PG70/30(flavoring is PG 20% of the total blend) and I add .5ml of VG and another .25 ml of flavor. How can I tell what the final nic level and mixture ratio will be?

Any help would be appreciated as I would like to stay as close as possible to 20-24 mg, but I'd be fine with 19-20. Just don't know how much more flavoring and VG I can add and still maintain that nic level.

Here's one way -

5 x 24 = 120, so if you use your new total ml as the divisor, you will get your nic %

in your example, 120/(5+.5+.25) = 20.87mg

6ml will give you 20mg
