Has anyone tried measuring the number of drops in 1 ml of different liquids? The pg I am using measures nearly 38 drops per ml, whereas vg measures 24 drops and water 23 drops. I am using identical droppers. The pg count seems way out, and I am thinking something might be wrong. It's a mail order pg from an animal supply store somewhere in the midwest. Anyone with ideas what might be wrong, or is this normal?

Nothing is Wrong. In Fact, Everything is Right with the Universe.

If Two Liquids of Different Viscosities had the Same Amount of Drops per ml then I would be Worried.

The Volume of a Drop is a Function of Three Major Components.

One is the Cross Sectional area of the Dropper Opening. The Viscosity of the Liquid. And the Surface Tension of a Liquid.

Thanks guys for your response. So I assume you are both ruling out any problems with my pg then? 38 drops per ml is a big discrepancy.

I would Double Check the amount of Drops for All 3 of those Liquids.

Usually, PG has a Similar Viscosity as Water. So the Drops/ml should be Similar. And VG is Usual Much Thicker than Water, so you should get Less Drops/ml.

Water is a Baseline because Tap Water or Bottled Water or Sea Water or just About Any Water has the same amount of Drops/ml.
