I was wondering if someone would be kind enough to do the basic maths and tell me how many mls of 72 I would need to add to 50mls to get approx 18mg (I don't need to be exact...please see next reply for why).

For 18mg, you want to mix 1 part nic with 4 parts juice. You need to add a quarter of 50ml to the 50ml which is 12.5ml.

To make any amount: working towards an 18mg target juice with 72mg base, just work out a quarter the amount of juice you want to add to and pour that amount of nic to your juice. So if i've got 100ml juice, I would add 100/4=25ml nicotine to give me an 18mg juice. You'll end up with 125ml

You need to mix 3:1 for a 1/4 strength mix, you'll wind up on 14.4mg at 4:1

I know where you are coming from but that's not the convention. Steam engine agrees with me. You should be dividing the 72mg nic across 4 parts of juice.

Fair enough, but I see you're mixing to get 50ml. The original question was "how many mls of 72 I would need to add to 50mls to get approx 18mg". You're adding to 37.5ml. My answer gets you 66.7ml after mixing.

I've just realised that. Yes, it's 66.7.

RE: short fills...any point?
As an alternative to calculating how much 72mg nic you need to add into a shortfill - why not just make up your own nic-shots?

2.5ml of 72mg + 7.5ml of VG = 1 x 10ml 18mg nic shot

You can make 400 of these from 1 litre of nicotine
If a nic-shot costs 50p (no idea if that's right, and i'm sure it's often more) and the nicotine has cost you £40 (say) then a saving of >£150 per litre with VG factored in.

Not going to work very well as they want 18mg finished product.

And it adds an unnecessary mixing step to the process.

Sounds like a full time job.
