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.
The default proportions — 30, 50, 20 — are a perfumery habit, not a rule. All three fields are free: the tool splits the total you give according to the proportions you set, and says when they do not add up to 100 %.
Splits a total number of drops into three proportions.
What it computes
- the number of drops for each of the three parts, from a total and three proportions
- counts to one decimal, because a pro-rata split rarely lands on whole drops
- what it did when the three proportions do not add up to a hundred: it splits the total pro rata, and says so, rather than correcting your figures without telling you
What it does not do
The three fields are free. The 30/50/20 split offered as an example is a perfumery usage, not a rule, and the tool proposes no oils, no pairings and no quantity to prepare.
The other tools
Each one computes from the quantities you enter.
- 🧪 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.
- ⚖️ 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.
