Please check my maths and logic

Heya guys

I'm getting ready to do some mixing and I want someone to check my maths before I go ahead. I am, to be honest, a shitful cook and I'm sure that messing up my measurements is one of my problems!

I have:

a Pimps Butterscotch doubler from JW (obviously 0mg)
100 mg stregth unflavored nic
50/50 PG/VG liquid

I want to end up with 20 mg strength nic with the standard strength of Pimps Butterscotch. For the sake of simplicity let's say that I want to make 10 ml. Furthermore, let's not worry about the PG/VG ratio.

According to my calcs I would combine

2 ml of the unflavored nic
4.7 ml of the unflavored pg/vg
3.3 ml of the Pimps Butterscotch

Logic check:

To reduce the unflavored nic from 100mg to 20mg I need to dilute 1 part of it with 5 equal parts of 0mg liquid.

A doubler from JW is twice the strength as a standard vape mix, therefore to achieve standard stregth I need to mix 1 part doubler with 2 equal parts unflavored liquid.

The total the doubler and unflavored PG/VG therefore must equal 5 times the amount of nic liquid.

The total of doubler used should be 1/3 of the total amount produced.

The ejuice calc I checked on agrees ... but that's only valid IF my logic re the doubler is correct.

Over to you.

2ml unflavoured 100mg nic.

5ml doubler.

leaves 3ml required of PG or VG or both

You say it's a doubler but 3.3ml would be the amount for a tripler


eJuice Recipe Calculator

standard vape on it's own 100%
doubler use 50% in your final mix
tripler use 33.333333% in your final mix.

 

I use a simpler method.
make 10ml of 20mg/ml liquid you need 200mg of nic.
so its obvious you need 2ml of the 100mg/ml.

its also obvious that ideally you want to use 5ml of doubler in the 10ml. its a doubler.

that leaves 3ml of the pg/vg

so 1.5ml is vg, which makes it 15% vg at the end of it assuming all the rest is straight pg,.

easy.

 

Thanks guys - I knew there was something wrong but couldn't figured what be.comse the maths was right.

I figured it had to be my logic (hence the tedious post)


Vape on!
