I often get asked about essential oil conversions and how to dilute essential oils, so I thought this would be a fitting blog post! I know how it feels to be in the midst of formulating new and exciting recipes using essential oils only to discover that I have no idea how many drops are in drams, ounces, or milliliters. This inevitably leads to a lot of funny calculations that cause a headache more than anything else. Oh, and forget converting milliliters to ounces and vice versa! We’re here to simplify things amiright?
Essential Oil Conversions and Dilutions
Once you have this simple list in tow, converting essential oils into the right measurement you’re looking for should be a breeze. I’ll also go over briefly how to dilute essential oils since I’ve already written a post on that topic.
Also, keep in mind that every essential oil is different and their drops may be larger or smaller than others depending on their viscosity (thickness). I know for a fact that trying to measure out an oil such a benzoin (a lovely vanilla smelling eo) in drops is pretty much impossible. Same goes for vetiver and other thick essential oils so keep that in mind when converting!
Essential Oil Conversions
Below I’ve listed the most common units of measure you may need for converting essential oils.
1 ml (aka .033 ounces or .27 drams) – 20 drops
3.75 ml (1/8 ounce) – 75 drops
5 ml (aka 1/6 ounce – this is the common size for small essential oil bottles) – 100 drops
7.5 ml (1/4 ounce) – 150 drops
10 ml (aka 1/3 ounce) – 200 drops
15 ml (1/2 ounce – this is the common size for medium size essential oil bottles) – 300 drops if filled to the shoulder. Some EO companies do not do this and are often 250 drops.
30 ml (1 ounce – this is the common size for large essential oil bottles) – 600 drops
1 dram – 74 drops (this is a very old unit of mass from Ancient Greece that is still used in aromatherapy today)
1/8 teaspoon – 12.5 drops
¼ teaspoon – 25 drops
½ teaspoon – 50 drops
¾ teaspoon – 75 drops
1 teaspoon (aka 1/8 ounce)– 100 drops
1 TB (aka 15ml, ½ ounce, or 3 teaspoons) – 300 drops
1 ounce (aka 30 ml or 2 TB) – 600 drops
2 ounces (aka 60 ml, 4 TB, or ¼ cup) – 1200 drops
4 ounces (aka 120 ml, 8 TB, or ½ cup) – 2400 drops
6 ounces – (aka 180 ml, 12 TB, or ¾ cup) – 3600 drops
8 ounces – (aka 240 ml, 16 TB, or 1 cup) – 4800 drops
Essential Oil Dilutions
Dilutions can be a bit tricky and really boils down to a person’s constitution, age, and whether or not they are pregnant or breast feeding. These conditions alone will determine what dilution you need. Always be sure to do your research for what you need before you begin.
1 % dilution
5 ml = 1/6oz = 100 drops – 1% of 100 is 1 drop
10 ml = 1/3oz = 200 drops – 1% of 200 is 2 drops
15 ml = 1/2oz = 300 drops – 1% of 300 is 3 drops
30 ml = 1oz = 600 drops – 1% of 600 is 6 drops
5 ml = 1/6oz = 100 drops – 2% of 100 is 2 drop
10 ml = 1/3oz = 200 drops – 2% of 200 is 4 drops
15 ml = 1/2oz = 300 drops – 2% of 300 is 6 drops
30 ml = 1oz = 600 drops – 2% of 600 is 12 drops

Essential Oil Dilutions for Special Situations
