Nicotine contradiction on Steam engine & Potv calc

[Trotters]

Here is a pic of my nicotine. 72mg or 7.2% PG 100%.

On steam engine where you put nicotine strength i put 7.2% at 100 PG and on the recipe it says to add 12.50ml or 12.94g for a 30ml batch.

When i go on POTV calc i put nicotine as 72mg at 100% Pg and that says to add 1.25ml or 1.29%.

Which is correct? And why is there a 10ml contradiction between the sites?

I can give more info if needed.

Thanks

It looks like the 12.5 ml would be the amount I would put in for 10x30ml (300ml)
A 30ml batch at 3mg of nic is correct at 1.25ml
I'm quite sure of this but also quite new to mixing so would like this confirmed befor you mix a batch but can definitely say that 12.5ml is a hell of a lot

Potv looks correct to me 1.25ml for 30ml

72mg/ml nic

You want 3mg/ml or 90mg/30ml

90/72 = 1.25

If you input the base nic' as a percentage, you have to input the target strength as a percentage also. I think you might have input the target strength as 3% rather than 0.3%.

Yes, easy mistake. It's 0.3% or 3mg.

Yep, youre right. Ive just found an old bottle that shows 0.3% 3mg. Schoolboy error.

@Trotters how do you find the nicotine from lucemill?
Been thinking of trying them out for my base supplies?
Thanks

With nicotine that's 72mg divide the 72 with the strength u require so I use 6mg so 6÷72 =12 so for every 12ml of liquid I need 1ml of nicotine.
