Question for mixing by weight

[bwh79]

Well, since different liquids have different weights, that means you have to calculate weight ratio of each specific liquid to get exact ratio.

If you're trying to exactly re-create, mixing by weight, a recipe given in volume, then yes, you will have to convert. But if you're creating or tweaking recipes on your own, "percent by weight" is just as valid as "percent by volume." Weight won't give the same results as volume, but the results it does give are no less valid, just different.

Example:

5ml of PG (5.18g)
5ml of VG (6.305g)
TOTAL: 10ml (11.485g)
PG content "by volume" - 5ml of 10ml total: 50% PG by volume
PG content "by weight" - 5.18g of 11.485g total: approx. 45.1% PG by weight

5g PG (4.826ml)
5g VG (3.965ml)
TOTAL: 10g (8.791ml)
PG content "by volume" - 4.826ml of 8.791ml total: approx. 54.9% PG by volume
PG content "by weight" - 5g of 10g total: 50% PG by weight

So as you can see, a statement like "50% PG" is just as valid for weight as it is for volume, you just have to know which one you're talking about.

(One might argue weight is even more precise than volume, since a single drop weighs in at about .04g, and the scales we use have resolution of .01g. I defy you to get repeatable precision on the order of "accurate to within less than a drop" using syringes.)

I like to mix by weight and use e-liquid recipes.xxx Their calculator allows for multiple flavors/

Question to all - I'm using e-liquid-recipes calculator. Do I need to have "use manufacturer specific gravities" checked or unchecked in preferences? And it seems that way more often than not, the ml and grams listed for a given flavor are the exact same (although notably different on the VG base). Is that normal...?

I have a capable scale, and the idea of just plugging in those weights as displayed by e-liquid-recipes is very enticing.

I'm not sure about that piece of Software. But in Most, if you Uncheck the "use manufacturer specific gravities" that you need to Enter your Own Values.

The Reason that you are seeing the ml's and the grams for Flavorings as the same Value is Because for Most Flavorings, 1ml = 1g.

Yes... 1ml of Pure VG weighs More than 1g. Or anything else that is used in a Mix. Many people use 1ml of VG = 1.3g

And then use 1ml = 1g for PG, Water and or Alcohol and Flavorings. It just makes looking at a Recipe easier. And since the Numbers in a Recipe are Based on Taste, not Numerical Absolutes, it works well for all but a Few.

Like i said, i have tried 2 times, didn't ended up good. Maybe my calculations were wrong (in fact they must have been wrong otherwise i wouldn't pour the liquid down the drain) but i find it much more simple to calculate % in volume then weight
One more time, no bashing intended from my side, i was just curious

I would go with what Yields the Best Results.

But if you have a Recipe that you know Tastes good, that is - Not a New recipe, that is in ml's, it Isn't a Big Leap to convert ml's to grams. It's just a Different Unit of Measure.

I have a capable scale, and the idea of just plugging in those weights as displayed by e-liquid-recipes is very enticing.

I have measured many many flavors with a very accurate machine and almost all of the flavors I measured were between 1.04 and 1.03 in specific gravity.
A few were very thin, (mostly FW flavors and closer to 1.01-1.02) but they were all, for the most part, close enough to 1.04 to satisfy my very (very very, lol) OCD nature so I plugged that value into all of my flavors in New Calculator to try and I have never looked back.

Just use 1.04 g per ml and you'll be good to go.

 

[Sloth Tonight]

Thanks all. Will be using this method from now on. Much more up my alley. Despise syringes, but love the act of creating eliquid. I enjoy using the scale in the kitchen and am happy to put it to another use

 

[fishwater]

I just started mixing my own & went right to the scale. I don't want to bother with all the additional clean up. I can mix in the bottle if I want & it literally takes a few minutes. This gives me more time for mixing & vaping vs cleaning. I use e-liquid recipes & it converts all the recipes to grams automatically using mfr specific gravities, simple & accurate enough for me.

 

[jb58]

I haven't converted mine to specific gravity but I only have a few recipes so far and they have come out fine.

JuiceCalculator has a setting so that when you add new flavors to your inventory, the grams per ml value can be automatically set to 1.04 as a default, or whatever number you want to use.
You can still change the value manually but this setting alleviates the burden of having to add the value for each new flavor you add to your inventory.

Yea, I use 1.03. Very close. I usually get about .03g to a drop. So even in a high percentage recipe, how far off can you be? Certainly a lot more accurate than all but the most stringent volumetric device. Also, unless you are converting an existing recipe from ml, it doesn't really matter as long as you are consistent and weighing is the best way that I have found to be consistent.

It really is that simple. I think you are going to like the way it works out for you.

I have said it a bunch of times but I am going to say it again so I can say I said it a hundred time. Measuring by volume is going to go the way of the Evod. Some day in the not to distant future, we are going to be saying " Remember when we all use to use syringes and had all that mess. I can't believe how hard it was before every one switched to weighing"

 

[Yerba]

Ok, I'm sold! I'm getting into mix by weight.
Really tired of cleaning syringes.
So what kind of scales you guys recommend?
I know it should read at .01 minimum, capable of reset to 0 after each component is added, and that's all I'm sure so far.
Also, very important at this moment in my life, must be in the up-to-$50 range.
Asking this because there are plenty of brands/specifications/prices out there, very confusing.

 

[Capt.shay]

A lot of people recommend this one:

Amazon.com: American Weigh Scales LB-501 Digital Kitchen Scale: Aws Digital Scale: Kitchen & Dining

But I tried both and I am going back to this one:

500g x 0.01g High Precision Digital Scale SF-400D2 Counting w/ USB Wall Adapter

 

[fishwater]

I have the first one recommended, the AWS, does all I need it to do.

 

[Capt.shay]

It works just fine. My issues with it verse the other were a slower ramp up to show your weight, smaller numbers to read and it shuts off automatically.

 

[Sloth Tonight]

I have the AWS, I've never had it shut off automatically...how long is the timer?

I mixed my first juice ever by weight today. SO much better than syringes.

 

[Sloth Tonight]

I just answered my own question...according to Amazon it will not shut off if it is plugged in...I've always used it plugged in.

 

[zoiDman]

For anyone who is considering buying (or has) a Scale, these are kinda Necessary...

You should also know how (or if) your scale can be Calibrated. And what Weights it takes to do so.

 

[fishwater]

The AWS scale comes with calibration weights already.

 

[oplholik]

I just use US coins, their weights can be found online doing a Google search.
