Essential Oil Dilution Calculator: Percent to Drops
Turns a volume and a percentage into drops and millilitres of essential oil, at the drops-per-millilitre rate you set. It proposes no percentage.
Result
A concentration is not a recommendation for use.
Understanding the calculation
Drops = volume (ml) × percentage / 100 × drops per ml
Carrier = volume − volume of essential oil; 1 fl oz = 29.5735 ml
Drops per millilitre is a convention, not a constant. It depends on the oil's viscosity, on the dropper and on temperature — which is why the field is left empty for you to fill in. The tool converts; it does not decide which percentage is appropriate.
Turns a volume and a percentage into a number of drops of essential oil. To convert only a volume, from drops to millilitres or back, see the unit converter.
What it computes
- the number of drops, for the volume and the percentage you enter
- the corresponding volume of essential oil, in millilitres
- the same figures at the drops-per-millilitre rate you set, because a drop is not a unit: its volume depends on the dropper and on the oil
What it does not do
It proposes no percentage. A dilution rate is a choice that depends on the preparation, the oil and the person making it — the tool does not make that choice, and does not name who a preparation is for.
The other tools
Each one computes from the quantities you enter.
- 🎭 Essential Oil Blend Ratio Calculator: Top, Middle, Base Splits a total number of drops into top, middle and base notes at the proportions you set, to one decimal. It proposes no oils and no pairings.
- ⚖️ Essential Oil Drops to ml, tsp and fl oz Converter Converts essential oil volumes between drops, millilitres, teaspoons, tablespoons and fluid ounces, at the drops-per-ml rate you set. No grams.
- ⚗️ Extraction Yield Calculator: Oil Mass as a Percentage Divides the mass of oil obtained by the mass of plant material charged: yield in percent, grams per kilogram, kilograms of material per kilogram of oil.
