Cheers Billy.

Don't suppose ya can tell me the forumula, so I can finally make this blasted JAVA applet for my phone with it?

Hi Storm,

First you calculate the total number of drops which is the quantity in ml * the drops per std 1ml.

5ml * 20 = 100 drops

Next you get the proportion of PG with nic as

(the desired strength in ml / the nic base strength in ml) * 100 rounded.

12ml / 52ml = 0.23 * 100 = 23%

PG/VG no nic percent is 100 - PG/VG nic percent

100 - 23 = 77%

Now you have all the percentages

If you have a water dilution and/or flavour percentage deduct it from the No nic VG mix percentage

Water: 77 - 5 = 72% no nic

Flavour: 72 - 12 = 60% no nic

Final calculations are the different percentages of the total number of drops...

PG/VG nic 77% of 100 drops

PG/VG no nic 60% of 100 drops

Water dilution 5% of 100 drops

Flavour 12% of 100 drops

Hope this helps with your java applet.

Brian.
