I think so. I just use a coin with the least wear on it, should be close enough for us, I think.
Meh, I lost my AWS weights...does the coin trick work just as well?
Using a Coin(s) or any other Known Weight is Great for Checking that a Scale is in Calibration.
But to Do Calibration on the Scale I have, it asks you to Place a 200g weight (I think) on it when it tells you to. And then to Remove the Weight after it does some Thinking. I'm not sure how well adding a Pile of Coins would work?
Maybe you could put them in a Bag or Something and adjust the Total Weight for the weight of the Bag?
For the Price of a Standard(s) or a Standard Set, I would just buy them.
Yeah, for yours, messing with the coins would probably more trouble than it's worth.
The 1 = 1 constant should work fine if you're mixing for yourself in small batches, like 30 mls max. Also, if you're using other people's recipes that's probably what they use, so best to stick to it.
It's very time consuming to look up/figure out specific gravities, then enter them into your calc, but maybe it's ultimately worth the hassle. It'd be great if they were printed right on the bottle. Take a look at this list of TFA flavors for an idea of how much variance there actually is from that 1 = 1 rule.
Here's a list I compiled of all TFA flavors and their weight • /r/DIY_eJuice
The majority on that list are in the 1.02-1.04 range, but there are some notable deviations. For example, grapefruit at 0.928. If you're using 1=1, and formulate a recipe using that flavor with other flavors in the 1.05 range, your end result is going to be heavy on the grapefruit and light on the other flavors, and the larger the batch, the more off it's going to be.
I think a lot of it has to do with how you formulate in your own mind the mixes you create. If you know the SG of your flavorings, you can still use the 1=1 constant and just adjust your percentages up or down accordingly, (as in, bump the percentage down a bit for grapefruit) though that's still mostly guesswork. For me it's just easier to already have the actual SG entered into my calc ( I use New Calculator to try ). That way it's consistent, and accurate for any size batch I care to make.
Just my opinion though.
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 use scale, you have to be sure that the scale is really precise one, and then if you use flavor from multiple manufacturers you have to measure each and every one of them if you want to be on spot for larger quantities. When you calculate in % you don't need scale or conversions for each specific type of liquid. All you need is a good quality syringes or measures and you are good to go. Way less possibility to make mistake. At least that's the way i see it. I may be wrong too, but % has been working flawlessly for me so far
I calculate in % and mix by weight. The specific gravities of all my flavors are already entered into my calculator. It does all the work. I can use the results to mix using whatever method I choose, by weight, by volume, or by drops. I don't understand your logic.
Because 0.92 is less than 1.00, and the higher the quantity, the greater the inaccuracy?
If my goal is to have a flavor work proportionately well with another flavor, and have consistent results over a variety of batch sizes, I should be calculating using actual specific gravities, no?
Or am I digging myself into a hole of erroneous assumptions?
Not Disagreeing that if you use a Different gram per ml amount than the Actual Value that you will be Off.
But if I'm Off .08% for a given Flavor when I Mix 10ml of Finished e-liquid, why would I be Off Any More (or Any Less) when I Mix 100ml? Or a 1,000ml? Or a Tank Trunk full?
As long as My Error in weighing Doesn't Change, Aren't I going to be Off by .08% for Any Amount that I Make?
You're probably right? To my mind, the more you make, the more off it's going to be. I do not have the math skills to back that assumption up. Maybe someone reading this does, and can explain it? If you do, please, out with it!
I think sometimes what happens when thinking about Error is one Forgets that Yes, when you make a Larger Amount, the Amount you Should have for a Given Flavor is Incorrect by a Larger Amount. But there is Also a Larger amount of Total Liquid. (ie: There is More VG and or VG/PG, or Other Flavors.) It is All Directly Proportional.
OK…
Say I’m going to make 10ml of a Flavored Mix that calls for 10% Flavoring. So I would need to add 1ml of Flavoring. And my Flavoring weighs Exactly 1 gram per ml. So I should add Exactly 1g of Flavoring.
But I don’t. I add .95 ml because I used the Wrong g/ml
Now I go to make 1,000ml with the Same Recipe. 10% should be 100ml of Flavoring. But once again, since my g/ml was wrong, I don’t add 100ml, I Only Add 95 ml’s.
Now I look at the Two Mixes.
In the 10ml Mix, I’m off by a Very Little Amount. Only .05 ml’s. That Not too bad.
In the 1,000ml Mix, I’m off by a By a Huge Amount. A Whopping 5ml !!! Yikes. That is Going to Taste Totally Different.
Or is it?
In the 10ml Mix my Error was 5%. .95/1.0 = .95 and 1 -.95 = .05 and .05 x 100 = 5%
In the 1,000ml Mix my Error was 5%. 95/100 = .95 and 1 -.95 = .05 and .05 x 100 = 5%
Hummm. Exactly the Same.
So Yeah, in the 1,000ml Mix, the Difference between what I Added and what I Should have Added was Large. Much Larger that the Difference in the 10ml Batch. But the Percentage Difference was Exactly the Same.
So the Two Batches Taste the Same.
If I’m off by 5% (or Any %) for the amount of Flavoring I should be Adding, It doesn’t matter what Total Amount of the Finished e-Liquid is. Any Amount of Finished e-Liquid will have a 5% Error in the Amount of Flavoring used.

I'm wondering if it really matters. When I was using drops for flavoring, I used say, 30 drops per ml when mixing a new flavor to test. If it wasn't to my liking, I'd add, or take away to suit my taste. Wouldn't it be the same way with using say, 1.03grams to a ml. Just adjust till it tasted right to you. Doing a new mix there are going to be some adjustments usually anyway. Am I making sense here?
This is Something that Many have a Hard time with.
That Repeatability and Consistency are what Matters. Not trying to be to Achieve High Degrees of Accuracy to an Arbitrary Numerical Value.
What is the Difference if you use 1g per 1ml for All Flavorings? The Taste will tell you if the Recipe is Right. Not the Numerical Values.
Right, and when you make an adjustment, leave the 1.0 or whatever you used, and adjust the percentages.
That's the Consistency part.
And if One fails to be Consistent, then Repeatability can't be Maintained. And that is when People Struggle. And DIY can be Evil.
