You're overthinking it. Nicotine is almost exactly 1 gram/milliliter, so a solution of 100mg/ml is 10% by volume, no matter what the carrier liquid. If we're talking percent by weight (but we're not, and you said so yourself), then yes, it would matter what the density of the carrier liquid is. But for percent by volume, 100mg/ml is 10% or very very close to it (technically nicotine is 1.01g/ml, so 100mg/ml would be 100/1010 = 0.99009900... or 9.9009%).

Not if the base is VG, which weighs 1261mg per ml. Volume isn't the problem. For every 1261mg there is 72mg of nicotine. That's less than 72%. So the description is wrong. If the base liquid weighed 1000mg per ml, as most liquids do, then the 72mg would be 72%. The volume is the volume but the ingredients are of different amounts. In the case of VG, 72mg per 1261mg is less than 72mg per 1000mg. More of one and less of the other or vise versa doesn't change the total volume. It just means there is either more or less of each ingredient.
So if it is 72mg per 1261mg (1ml) then it isn't 72%. It's less !.
All i want to know is.....which is it, 72% per ml or 72mg per ml ?. Both these amounts are completely different. And i don't know the answer because it doesn't say on the label.
Yes if the base is VG. Yes if the base is PG. Yes if the base is friggin cognac or strawberry jam. 100mg of nicotine takes up a volume of 0.1ml. So if the nicotine content is 100mg per ml then that's the same as "0.1ml nicotine per ml total," also known as "10% nicotine by volume," regardless of what the other 0.9ml is made up of (or how much it weighs).
If it's labeled as (and actually contains) "100mg/ml" then it is 10% by volume, no matter what the carrier liquid is. It is not necessarily 10% by weight, but it is, absolutely 10% by volume.
By weight? You're right, it's not 7.2% by weight. But it is 7.2% by volume. You seem to be under the impression that "percent" must necessarily mean "by weight," but that's not the case. "Percent" just measures "parts of the whole." "The whole" can be measured by weight, or by volume, or by cost, time, distance, or by any other factor by which you could conceivably measure something, and, and here's the key, they are not necessarily equivalent to one another.
By way of example, let's say that I'm taking a trip to Washington. First I get in my car and travel from my house to the airport, and then I take a plane from the airport to Washington. Depending on where I live, my car ride to the airport might take just as long as my flight to Washington. But of course the plane moves a lot faster than my car. So while the car ride might conceivably be 50% of the journey by time, it's still far less than 50% of the journey by distance. I wouldn't say something like "I drove halfway there" (that would imply distance traveled, of which the car ride was significantly less than half), but it wouldn't be wrong for me to say "the car ride was half my trip," as long as I was talking about half the time it took, and not half the distance traveled.
Does the volume matter ?. Is the volume of nicotine more important than the weight ?. There are more mg's of nicotine per 1261mg of VG nicotine liquid by it's % weight than there is in 1000mg's of PG nicotine liquid by it's % weight. Forget the volume !. The point, my point is that the % weight of nicotine in 1261mg's of VG nicotine liquid is not the same as the % weight of nicotine in 1000mg's of PG nicotine liquid. It doesn't matter how much space this stuff takes up. Whoever said the volume is more important than weight ?. That's why the % symbol shouldn't be used to describe how much nicotine is in a ml of nicotine liquid.
More mg's is more mg's regardless of the volume.
So is 72mg's 72% of 1261mg ?
No !.
And you can't just disregard the weight just because the bottle says ml. The weight is just as important as the volume, if not more so.
If nicotine is measured in mg's then the label should say exactly how many mg's there are per ml.
Nicotine is not measured by volume so the % symbol used to describe % by volume is a contradiction to how nicotine is measured.
So i have to take an educated guess and decide that the "72%" VG nicotine liquid i have is in fact 72mg's per ml. You see !. And not 72%.
That's MG's !.
That's MG's !.
You're right: most nic base states the percentage in mg (per ml). Some nic base however states the percentage of volume.
You're right that VG has a specific weight of 1.2613 g/cm³. Which means that 1 liter does not weigh exactly 1kg, like water almost does: 0.998 g/cm³. Or for this matter nic also almost does: 1.01 g/cm³.
Now if you'd have exactly 900ml of VG and you'd put in 100ml nic, that's exactly 10% if you look at the volume (ml) and not 10% if you look at the weight (101gr while you have 1135.17 grams of VG). So 1135.17 + 101 = 1236.17 total weight. And 101 of 1236.17 is ~ 8%

All these maths (sic) are potentially confusing the math challenged mixers. Simply put, if you are mixing 100mg/ml nic base by volume each ml has 100mg of nicotine. If you are mixing by weight makes sure you set your calculator for the density of each liquid use.
Yes sorry @PurpleDragon just ignore all those posts about numbers, best advice i read here, was not to mix 1 liter but start with a small amount and see if you like it. Once you're comfortable with your liquid, you can mix liters.
One thing to keep in mind is what flavours you intend to use. Most flavours are PG based, some need 1% flavoring but some need 15%. This alters the ratios of your juice.
Whatever. I'm done. I don't have time to argue with you about this. Well I do, I just don't want to. #hashtagSeeYaPal

No one is arguing.
Just pointing out that nicotine is measured by weight (mg) and not volume.
I've been talking about mg's this entire time.
You decide to ingore that context and wind on about volume, and then call "me" an idiot !. It's as if you deliberately want to make me look stupid.
