Australian Doubler Nicotine Calculator

  1. Please note your starting nicotine must be at least double the strength of your target nicotine.
  2. The "doubler volume" should be half the size of the total bottle volume - doublers arrive half-full.
  3. I'll try to add VG/PG ratios in the future, but in the mean time I would recommend adding VG on top of your nicotine to arrive at an approximately 70% VG e-liquid (as most doubler e-liquids contain between 10-25% PG from their flavour concentrates).
