Work out essential oil dilution instantly with clear inputs, formula shown and shareable results.
Essential oil volume is the carrier volume times the dilution percentage, converted to drops at the standard twenty drops per millilitre. Dilution is the main safety control in aromatherapy, and drop counts vary with viscosity, which is why weighing is more reliable than counting for repeatable blends.
Oil volume
ml = carrier oil ml x dilution percentage
Drops
drops = oil ml x drops per ml
Dilution guidance is general information, not medical advice. Check contraindications for each oil before use on skin.
