How many drops in a 15ml essential oil bottle?
Have you ever been happily doing Make And Takes Workshops at home with your favorite essential oils and suddenly realized the bottles are expressed in ml, and all you know is about ounces?
That’s because the essential oils trend is mainly coming from France where the only unit measure is the decimal system.
So, you are surprised to find out that there are different units of measurement to convert from drops to ounces to milliliters?
Sometimes, you also have a downline calling you and asking: “how many drops in 5ml essential oil“?
And, because you were not (yet) prepared, this leads to looking over the internet to find out an easy explanation!
Here are the best tips to keep with you when it comes to converting ounces to milliliters and then milliliters to drops to diluting your favorite essential oils with ease.
Essential Oil Conversion table
1/8th oz >>> 3.75 ml
1/4th oz >>> 7.5 ml
1/2 oz >>> 15 ml
1 oz >>> 30 ml
4 oz >>> 120 ml
8 oz >>> 237 ml

Easy Oil Stuff
The best essential oils come in the standard size of 15 mL bottles while expensive and premium oils come in 5 mL bottles. Many distributors like to sample, share or distribute oils in smaller 2mL bottles.
Now, if you don’t want to go into this big headache here is the easy formula to find out how many drops in a 5ml essential oil bottle and how many drops in a 15ml bottle.
- 2mL – 25-30 drops
- 5 mL Bottle – 100-120 drops
- 15mL Bottle – 320-400 drops
Note that there is a range and not an exact number because essential oils drop varies in size according to the viscosity (thickness) of the oil…
The thicker the oil, the fewer drops per mL you’re gonna get. On the other hand, the thinner the oil the more drops per mL you’re gonna get.
Do you use a pipette to measure how many drops per ml?
Thicker or heavier oils like Patchouli or Sandalwood have a tendency to become larger on the end of pipettes, whereas the thin essential oils like some Orange citrus essential oils will produce a much smaller drop and drip off more quickly, producing many more drops per mL.
