Nic 1....................10 drops
Nic 2....................5 drops
VG.......................8 drops
Flavor 1................8 drops
Flavor 2................2 drops
TOTAL DROPS........33
Now divide each value by the total drops of 33
Nic 1....................10 drops.....10/33 = .30
Nic 2....................5 drops.......5/33 = .15
VG.......................8 drops.......8/33 = .24
Flavor 1................8 drops.......8/33 = .24
Flavor 2................2 drops.......2/33 = .06
NOTE - there is a rounding error of .01
If you're familiar with Excel, you can pop that into it and you've got yourself a quick calculator.
Example...using three columns A, B, and C, you'd enter the ingredient names into col A, the number of drops into col B, and then the formula for column C would be
=b1/sum($b$1:$b$5)
Then just grab the cell handle and pull the formula down to copy it into each row.
Just throwing that out there...
