Find an
ejuice calculator to use!
The ratios (flavor percentage, PG/VG, nic) all are inter-related, so it's easy to make a math mistake.
I like
e-juicemeup, which is a program for PC, but there are also apps you can use.
You need to know the strength of your nic (you said 36) and whether it's in PG or VG or a blend.
You need to decide the ratio of PG/VG you want to end up with - this may depend on your equipment and preference - PG carries more flavor and has more throat-hit, but VG makes more vapor.
You need to choose a flavor percentage to try out - could be anywhere from 1% to 20% depending on recipes and flavoring strengths...
All we can tell from your starting point is this: with 36 mg nicotine going into your mix, each ml of nic base will put 36 milligrams into the bottle. So with a 10 ml bottle,
1 ml of base in there gets you 3.6 mg strength
juice
2 mls of base in there gets you 7.2 mg strength juice...etc.
