ejuice me up calculator accuracy?

[Dubby]

Made my first batch of juice today.

When I was making it I used a scale for everything except my nicotine (100mg in vg)
It called for .45 ml to make a 15ml bottle of 3mg. I pulled .45 into my syringe and then in the mix. The weight did not match what the weight on e-juice me up said.
It feels stronger than 3mg. Am I doing something wrong?

Could take a screen shot of the mix and post.
You have given us no information on the weight of nic in 100%VG.
What is that number you used?

I believe ejuicemeup has a preferences page to define specific gravities of e.g. your nic-base and I don't know what it's set to by default, so you should check that out.

Btw, 100mg vg nic-base, without any water added, has a specific gravity of 1.235, rounded up to 1.24, so the correct value in grams to add for your example would be 0.56g nic-base(0.45*1.24=0.558).

In addition to what mhertz said there is no guarantee that the syringes we purchase are very accurate. They can vary considerably. And have you calibrated your scale?

What are you doing wrong? Where to start

Seriously though, you are hardly explaining yourself in a manner that we might help you. What weight did the calc. say? What did your scale say?

Let's assume that your scale is working properly, then:

Weight of 100mg in VG: 1.235 grams per ml

.45 * 1.235 = .55575

Your calculator should have told you to add .56 grams of Nic. If not then you probably have your values set wrong.

Your scale should have told you that is how much the .45ml that you measured and added weighed. If not you measured wrong.

If the scale said you added greater than .56g then your mix may be slightly higher than target.
