Understanding the Formula
Our calculator uses the industry-standard conversion: 1 mL ≈ 20 drops. This remains the most consistent metric for standard glass pipettes used in 2026. For high-precision therapeutic blending, we recommend measuring by weight (grams), but for DIY and home use, the volume-to-drop ratio provides a safe and effective baseline.
Total Drops = (Volume mL) × (Dilution % / 100) × 20
