Accurate Flavour Weight Measurements

[memzey]

Exactly. I wonder how much difference the minute variances in specific gravity would actually make - very little I would think. The huge variance experienced by the OP point to something being out in the main component of the recipe. I wonder if that recipe’s author incorrectly assumed that 1g of VG = 1ml? The numbers roughly suggest that.

Is there a reliable list somewhere of specific gravities for all the different flavours on the market?

Just come back on line and been reading the thread.
I'm not aware of any calculator that specifies specific weight measurements for individual flavours. There are so many flavours, even combinations of flavours, that it would be impossible to fracture all these in.
In reality, there is hardly any difference in specific weight for flavours and as such most calculators will work on the flavour being 1.00 gm, mine included. If the flavour is based in PG, the specific weight will be 1.038. If the flavour is based in VG, the specific weight will be 1.260. I can't comment on other calculators but when using mine I've always found it to be accurate.

I was calculating a 120ml mix using an online recipe calculator and found the VG weight was over 10ml different. I'm really not overly bothered about precision but I felt that difference was too far off and I would have almost ended up with liquid spilling out of the top. You'd be surprised how much difference cumulative errors like that can make.

Hope it wasn't my calculator you was using

The detail the OP has gone into is distinguishing subtle differences between say TFA Marshmallow and TFA Blueberry when existing recipies won't be that specific and certainly mix calculators won't have been programmed in such detail.
As interested in vaping calculators @Richard Winter is I'm sure he'll confirm it would be a huge amount of work to achieve something pretty negligible when you factor in the number of flavour manufacturers and thousands upon thousands of individual flavours.

Quite right @StrawberryRipple, it would be impossible and iimpractible to do this for flavours, millions of them. There is so little difference. My calculator uses 1 and then adjust for the base liquid its in.

I think this is highly unlikely.

Happy with my settings

I don't think 1.07 for flavour is right.

Not sure what calculator was being used but if they assumed that they are wrong.
Nicotine = 1.01
PG = 1.038
VG = 1.260
Flavour = 1.
The tiny variations in the specific gravity of different flavours would be virtually unnoticeable.

Weighing liquid is too accurate for me. I like some natural random variation.

Mixing oneshots it makes no difference. I whack that in first, note the net weight & adjust the rest of the components as required. All oneshot bottles I've used are overfilled so just adjust PG to allow. At the end of the day would anybody be able to detect a variance to 2 decimal places anyway. Flavours are likely produced within a tolerance so one batch could be heavier than the next so measuring current stock will be no use if the next bottle comes from a different batch.
Too much overthinking a problem that isn't there maybe
