I can't thank all you "smarties" enough! The older I get the more I lose any math skills I once had.
Need math help, please

Steal away, it's only 5 minutes work on my side. Nothing special.
The longer you are away from something like math, the hard it is to recall how to do things.
Just curious. Did you mix up a new mg batch? How did it taste?
Because I've insomnia and need something to do I implemented DVap's formula into an Excel spreadsheet to make life easier for people without Mathematica or similar to do the work for them.
Calculator for Strengthening or Diluting E-Juices
It's very simple and isn't very shiny I'm afraid but it gives the correct answers!
Our fathers would have implemented the formula on a slide rule... just to circle back to a previous topic....

Slide rules are far more versatile than spreadsheets after all.

I made some DIY for a friend and he wanted it a higher mg so I made the flavor a bit stronger so he could add whatever additional nic he wanted. He said it worked great and he loves it.
I need to see if Dan added this to his calculator. It amazes me how I use to be able to figure out most things in my head and now there's nothing in there... it's blank.
Oh well, I AM blond!Thanks again everyone!

I have added it, but was waiting for a release statement
Looks like I got it, so it will be out soon.Dan

I like your presentation better than mine.
I used:
Conc = [(Vol1 * Conc1) + (Vol2 * Conc2)] / (Vol1 + Vol2)
and solved for Vol2 quite roundabout while you came up with the more direct Vol2 formula:
Vol2 = - (Vol1 * (Conc1 - Conc)) / (Conc2 - Conc)
My algebra is far too dodgy to get Vol2 all by itself... I might be a chemist, but I've always been weak with math!

I got in trouble awhile back when my wife let a friend redo the blond hair coloring she's preferred for many years over her natural brown.
The job didn't go well at all, and it took a professional to fix it, along with six weeks of her having to go with her natural brown.. she hated it.
I don't suppose it was a good idea that I tried to cheer her up with, "It's OK, dear, at least you can do math now".

Don't worry, I made several basic mistakes involving forgetting to reverse signs and similar while working it out by hand. My algebra is *very* rusty.

Just sounds like you haven't had to work with Ratios for a while. Math is like ridding a Bike. If you ever learned it, you can get it back with a little practice.

Yeah, but with friends like you guys I don't need to.
jynn, that's Sammy, a 25# Maine .... cat and the love of my life. He moved on a few years ago and I still miss him terribly.
