How is a perfume spray measured?

A perfume spray is typically measured in milliliters (ml) or ounces (oz), indicating the volume of the fragrance in the bottle. The concentration of the perfume, such as eau de toilette or parfum, also affects the potency and longevity of the scent. When dispensed, the spray mechanism releases a specific amount of fragrance per spray, often ranging from 0.1 to 0.2 ml, allowing users to control the application. Additionally, some brands may provide guidelines on the recommended number of sprays for optimal scent delivery.
