100ml metric system unit equals 3.38oz in the imperial unit. It’s a medium size and you can grab it in one hand. Usually, the perfume is stored in a glass bottle. The total weight won’t bypass 300 grams, a medium size cup of coffee.
Multiple factors influence the use time of a single 100ml perfume bottle.
Typically, a perfume bottle is with a pump sprayer. The pump capacity with every single press is the first influencing factor. For a sprayer pump with neck size of 13-15mm, every turn you press the pump leads to an ejection volume of 0.08 to 0.1ml. Pump with neck size 18-24mm has ejection volume of 0.2-0.3ml per turn.
There’re differences between a normal mist sprayer and an extremely slim mist sprayer. An extremely slim mist sprayer ejects half the volume of the normal sprayer. It’s about 0.12-0.15ml per turn with neck size of 18-24mm.
For light and refreshing perfume, you usually need 3-4 sprays that last a day without worries. For heavy and intensive perfume, it’s about 1-2 sprays.
So, let’s quickly do a simple calculation.
100ml | Light perfume | Heavy perfume |
Normal sprayer with neck size 13-15 | Around 317 days | Around 740 days |
Normal sprayer with neck size 18-24 | Around 114 days | Around 267 days |
Extreme slim mist sprayer with neck size 18-24 | Around 212 days | Around 494 days |
These are the maximum days you can use every day with a 100ml perfume bottle. You can estimate your budget of perfume cost with it.
