How Many Drops in e-liquids?

[fumerfrancaise]

Is it possible to work this out??? Say I have a 30ml bottle of High (18 strength) liquid. I drop each cart with 6-8 drops but can't figure out how many carts (approx) I can fill with a 30ml bottle? Would also be useful so that I could have a rough idea of how much nicotine I'm getting through in the day.

I'm betting that there are e-cig experts here who have already figured this out -so can save me masses of time and headaches trying to get the math done myself

Well, that's really going to depend on how hard you squeeze and how large the dripper opening is, and the viscosity of the liquid.

You can always drip your entire bottle into a glass or another bottle and count, then put it back.

around 112 cartrige if we count 30 drop per ml
30x30=900
900/8=112.5

1 US teaspoon = 4.92892159 ml See how many of your drops it takes to fill a tsp....ok, use a 1/4tsp and multiply by four. So at 18mg/ml, you have 88.7 mg of nicotine per tsp.
Take the number 5 for a tsp, just for time, you should have 61 of those tsp's in a 30 ml bottle. If there's 17 drops in a tsp, then 61X17=1037 drops in your bottle. (That's just for now, understand, you count your own!) So if your cart holds 5 drops per filling, you have 207.4 fills per bottle.
Always try to reference by milliliters, because every liquid has a different viscosity, so drops are not standard measure. Thick liquid, fewer drops. Goes to mixing your own liquids, always use ml measure to be sure!! Otherwise, every answer you get here will depend on the Poster's dropper and liquid, not necessarily the same as yours!

OMG....I second Bandit's post Kate -you must be a mathematical genius!! Got yours and liscab's meanings though thx. Would've helped tho if I'd mentioned I used Totally Wicked (Red Devil logo) liquid!
Will try this and Walrus method tomorrow just to satisfy my cruiosity.

Well, there's just no easier way to get how many drops in a milliliter, I guess. Geez, all you wanted was how many fills in your bottle, right? There it is. Fumer, Problem at hand was to find out how many drops were in the bottle.
Bandit, you're probably much better than me at posting pictures of ducklings falling off a curb and calling people Preachy..I prefer more meaningful exercise, that's just me.
I would be happy to walk you through it if you want, I just didn't have your dropper so couldn't really measure how many drops per milliliter you'd get. And they don't make measuring spoons for milliliters (unless you have an open graduated beaker, but those are mostly 2ml increments.). But this is the easiest way to do it. Using drops isn't very accurate. By the way, my "standard" dropper yields 40 drops per ml, but no liquid is "standard" viscosity, so the point is moot anyway.
Your 18mg/ml liquid yields 18mg X 30 ml = 540 mg nicotine.
