Combime Pre mixed for desired PG/VG ratio

[paddymx]

I have a problem with PG so I can't try Pre mixed flavors because they are mostly 80/20 or 70/30. I need 60/40. I've been wanting to try RY4 as it seems to be pretty popular so I ordered a 0mg RY4 PG from one vendor and a 0mg RY4 VG from another. I am waiting for a response on their exact specs but lets assume:

PG = 70/30
VG = 10/90

How much of each would I combine to reach 10ml @ 60/40?

This answer was wrong, corrected further down....

I'm not great with fractions, and honestly am using a calculator (ejuicemeup, using 10/90 as flavour input) for this so can't check the numbers manually, but:
80% 70/30
20% 10/90

So for 10ml you'd want 8ml 70/30, and 2ml 10/90.

If this is wrong someone will step in in short order and correct it.

Me neither.

I've tried ejuicemeup too. How did you come to the 10/90 input and how did you input it? I have tried using flavors as the premix levels @ 70/30 #1 and 10/90 #2 . No matter how I input it I get that "need more VG, can't have negative values" error message. I've tried, but, with every attempt I don't feel confident.

Thanks for the help. Looking for a simple formula . I too am not good with fractions or %'s. Hope someone has an answer.

You could use the Ejuice Recipe Calculator
you figure there is aprox. 20 to 25 drops in a ml so roughly say roughly 200 drops to 250 drops of juice in 10 ml , so 250 x 60% is 150 drops. 250 x 40% is 100 (but I suck at math, but thats what I come up with) lol

Thanks but I am combining juices of different %'s of PG and VG. If the %'s were 100% PG and VG it would be that simple, but they're not.

Thank for playing

I revisited the ejuicemeup and yea, I wasn't sure what I was doing and figured it wasn't correct.

Okay, pen and paper time, simplified maths that I think work properly.

70/30 can be looked at like 7/3 since you only want 10ml.

Now I just multiplied 7 (base PG) by numbers (starting at 8.5 since I knew 7*8 is 56/44 and 7*9 is 63/37) till I came up with very close to 60, the result of this fudging is 8.6. So my layman maths says 8.6ml of 70/30, and 1.4 of 10/90. to get 60.2/39.8!

I don't know if this is the correct way, again, but the numbers seem to work out. In fact, this is why I failed math in highschool...I'm going to have to bow out of here and let people who have a firm grasp of numbers step in and give solid calculations.

I know your doing 60pg and 40vg so im letting you know how many drops of each dear

What is the mixture you have of the pg and the one of vg
So your saying you have pg in like a 70/30 and a vg in a 30/70? still use each number drop of the 60/40
owell just trying to help

Yeah, this stuff makes my head hurt! I read and read and re read and still couldn't figure it out. I can somewhat follow converting the 70/30 to 60/40 and then thinking the balance is whats left for the VG. But, using that idea I can't do the same from the other direction.(10/90 to 60/40) ... Agreed, I know there is someone that this stuff is like falling out of bed for them.

Thanks

Just read your EDIT.

No its worse than that. One is 70/30 and the other is 10/90. I'm afraid that 60% of the 70/30 and 40% of the 10/90 will not equal a combined ratio of 60/40. Thanks for answering though.

Just got the specs.

PG 80/20
VG 20/80

Does this make it easier?

Not sure if I can explain how I got there, but your answer is:

2 parts of 80PG/20VG + 1 part of 20PG/80VG = 3 parts 60PG/40VG

For easier measuring you might want to go with 9 ml total rather than 10 ml total - that would be 6 ml of 80PG/20VG and 3 ml 20PG/80VG.

Thanks granny, I got an answer from a vendor that matches yours. I am waiting for permission to give them credit and perhaps the formula to reach the answer. Others might/will have different ratios to mix and I think it might be helpful.

For 10 ml:

You would mix it 2 parts PG mix to 1 part VG mix. Or in other words 66% or 6.6ml of the PG mix and 33% or 3.3ml of the VG mix to end up with 60% PG and 40% VG.

Here is the answer:
Abstract:
This is designed to combine a PG based pre mixed juice and a VG based pre mixed juice to reach a desired PG/VG ratio.

Note: Use ejuicemeup calculator tool to see the resulting nic level
You can fine tune it by playing with the number of decimal points in the test value. This test value assumes a 10 ml finished amount of liquid. Additional finished amounts are provided in the chart below.

Version 11.0.0 has just been released.

If you need to mix/combine Pre-Mixed eLiquids with different PG/VG ratios and would like to figure out what the resulting ratio is, I added a calculation function in the tools menu. Go to Tools, Nic Combine

You can calculate for Nic or ZERO Nic.
