What does pg / vg percentage mean?

[MadMax]

I have heard people on youtube talk about the percentages in liquid i assume??
What is it, and how does it relate to vaporizing? I heard it's got something to do with
harshness

Thanks

Percentages can be used to state the PG/VG ratio and also the nicotine content.

For example 70/30 juice would be 70% PG 30 % VG. Usually PG is the first number but I have seen vendors do it the other way around.

The nic percentage is the amount of nicotine in the juice. 1.8% = 18 mg of nicotine per mililiter, 1.2% equals 12mg per ml of juice. .6% = 6mg/ml etc...

PG (propylene glycol), VG (vegetable glycerin)

PG thinner viscosity and a througtier hit

VG more cloud, thicker but less flavor

I just did a test to find out myself. Went from 100% VG to a 70PG/30VG mix. Big difference. I plan to do 50/50 from now on.
