Hmm, seems silly they give different weights from different apps, surly there is a known weight of this stuff?
Cheers for that[emoji106] the app I'm using asks if it's Pg or vg nic on first set up, maybe they fecked up an corrected calculations.There are known weights. VG is 1.260 g/ml where as PG is at 1.038 g/m. flavourings can vary between 0.9g/ml and 1.2 g/ml even when PG pased though most of the recipes you will find tend to use a 1g/ml ratio for flavourings to keep simple.
anyway that calculation seems spot on, it sounds like the initial calculation must have used PG base for the Nic
