So i've done a lot of reading on this and there seems to be some info I dont understand. Are there any ejuice calculators that do accurate calculations by weight? I read that different liquids like pg/vg/nicotine/flavors have different weights, so 1ml of pg will weight different from 1ml of vg. I get this part. So then how do you do a 50/50 pg/vg? I'm assuming that 50/50 is by volume, not weight? I am getting so confused. Does that mean that nic base which is (x)mg/ml differs if its pg based or vg based? I recently got a bunch of stuff in, flavors, syringes, pipettes, vg, pg, 100mg nic, and the info is going over my head. I filled my first 20ml bottle today with a "grants vc" recipe and its steeping now, but after that experience I see how making recipes by weight, and not volume, is much easier, and more accurate. Someone help me out please
