How many drops of liquid are in 1 mL?

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?

That's why I always use the measured syringes when measuring nic, pg and vg. That's the most important part to get right. Most flavoring I'll use the syringes too but there are some that I know how many drops per ml and some that only use a drop or three so I'll use the pipettes.

Different drippers will make different size drops. Your experiment using three different liquids using the same dripper just shows how imprecise using drops is. A graduated syringe is a more accurate measuring device, for all intents and purposes.

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.

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.

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.

PG, in any type of dropper or syringe, is generally in the 40's for me. 46 with a standard dropper.

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.

What about soapy water?

That is why a Seasoned Poster will put "About Any" on his/her post to CYA.

LOL

BTW - vaping Soapy Water is Not Advisable.

Then you better use a syringe!
