Standard weights for ingredients

[kickflipsnnollies]

We need a list of weights, or at least specific gravity for all our ingredients. So if you know weighta, post some numbers. If you throw an accurate thermometer in it to check that'd be awesome. Density changes a lot with temperature. Please measure at least 10 ml, 100 would be better, and take an average. If you're comfortable giving your location that'd be great too, but an elevation without specific location info would work. This is a knowledge base for the public so please be as accurate and thorough as humanly possible. Think chemistry lab.

As soon as I can afford a scale I trust I'll post some of my own numbers.

I am afraid you are making things to look too difficult.

Changes in specific gravity due to temperature relatively small. When temperature for water changes from 60 F to 90F changes of specific gravity changes are only 0.5%. Too little to bother about.
Changes in specific gravity with pressure are even smaller.
So, we can forget about temperature and pressure.

Specific gravities of main ingredients (PG, VG, water) are known. Specific gravities of flavorings are relatively close to their main ingredient (usually PG) and it is almost impossible to gather data on all (most) flavorings anyway, unless manufacturers will post it on labels.

We need a list of weights

The weight of something depends on the amount. I think you meant to say "densities." And here they are:

Propylene Glycol ("PG"): 1.036 g/ml
Glycerol (Vegetable Glycerin/Glycerine, "VG"): 1.261 g/ml
Nicotine: 1.01 g/ml
Ethanol (Pure Grain Alcohol, "PGA"): 0.789 g/ml
Water (Distilled Water, "DW"): 0.999972 g/ml (at 4° C, where it reaches maximum density) (Just call it 1.0 since none of us probably have a scale with that kind of precision.)
