How many drops in an ounce of essential oils?

The number of drops in an ounce of essential oil can vary depending on the viscosity of the oil and the dropper used, but a common estimate is that there are approximately 600 drops in one ounce. This is based on the standard measurement of about 20 drops per milliliter, with one ounce equaling about 30 milliliters. Therefore, 30 ml multiplied by 20 drops/ml gives roughly 600 drops. Always check specific dropper sizes for accuracy.
