Question for mixing by weight

[Sloth Tonight]

Just tell it 0mg base and 0mg target. Since you don't care. Will it accept that? Or will it just tell you to use 0ml of that and give you amounts of PG and VG to add?

EDIT: Since you're not shooting for any particular target, it might be best to simplify. Tell it your target is 0mg, 100%PG (and if it asks, tell it your flavorings are 100% PG as well). Then it will give you a recipe with only PG and flavorings. Use your premade nic base as the "PG" value, and add the flavorings in the appropriate amount.


...oh, I sort of forgot what thread this was, though. This will work for measuring amounts in ml, but since we're mixing by weight, you will need to convert it to grams by hand, since the weight per ml given for PG in the calculator will not match that of your mostly-VG nic base. 90%VG, 6.4%PG and 3.6%nic (what you have if you made "90/10" with 36mg PG as the "10") is:

(.9 * 1.036) + (.064 * 1.261) + (.036 * 1.01) = 1.076734 g/ml
...scratch that...had my PG/VG values mixed up, and my nic math was off by a factor of 10...

90%VG, 9.64%PG and .36%nic:

(.9 * 1.261) + (.0964 * 1.036) + (.0036 * 1.01) = 1.2384064 g/ml

lol yep, kind of a screwy situation right? I'm too lazy to do math on the reg so I'm thinking I'll usually just tell it 0mg target. It then gives me PG and VG values, and I'm thinking of just adding those two weights together.

IE if I tell it I want 85% VG and I am using 5% flavorings, it will give me the weight for an additional 10% PG and 85% VG. If I add those together I'll have the weight of my 90/10 nicbase...(except the quick math test I did with a recipe yielded different results than when I honed it into be precise to my nicbase...but the difference was like .04mg )

lmao...I doubt anybody else out there managed to do this nonsense to themselves

ETA I think I just realized what you mean...so all I need to do on any given recipe is taken whatever total of ML of base it is calling for and mulyiply it by 1.2384064 g/ml. I just did that and it came out exactly as ELR told me a recipe would be when I fidgeted enough to get it exact. That's awesome man. Thank you

Bump

Because this thread was great and has some super helpfull info that people keep asking about.

 

[Sloth Tonight]

I'll second that bump...this thread changed how I mix (for the better)

 

[Susan~S]

I'll bump too. Can't imagine mixing any other way.

BTW - jambi posted this Today in another Thread...

The scale is less than 30 bucks. Rather than solicit opinions from a lot of people who prefer their volume method and maybe haven't tried mixing by weight, I'd encourage you to just pick up a scale and try it for yourself...

...Then you can come back here and rave about how you love it and you're never going to have to wash another syringe.

This video kind of put it all into perspective for me. Don't need to do all the math shown in the vid, your calc should do all that for you. The scale shown is the one you want. LB-501 by American Weigh Scales.

The Video is Diffinately Worth Watching is you are New or Considering Mixing with a Scale.

Nice thread indeed. Weight will always be more accurate. Just like in baking; professional chefs don't use cups, they weigh everything.
