Common perfume sizes
| Label | Exact mL | Sold as | Carry-on |
|---|---|---|---|
| 0.5 fl oz | 14.79 | about 15 mL | Fits |
| 1.0 fl oz | 29.57 | about 30 mL | Fits |

| 2.5 fl oz | 73.93 | about 75 mL | Fits |
| 3.4 fl oz | 100.6 | about 100 mL | Fits |

Brands round to a tidy mL size, so the ounce figure on the box is the conversion, which is why it looks odd.
Worth knowing
Perfume sizes are set in mL and converted for the US label. 50 mL is 1.69 US fl oz and 100 mL is 3.38, so the box says 1.7 and 3.4. The mL size is the real target and the ounce figure is a rounded conversion. That is also why two brands can both print 1.7 oz and differ by a fraction of a milliliter.
Price per mL is the fair way to compare sizes. A $90 bottle of 1.7 oz costs $1.79 per mL, $52.94 per fl oz. The same scent at $130 for 3.4 oz costs $1.29 per mL, $38.24 per fl oz. Larger bottles are often cheaper per mL, but only if you will use the perfume before it fades. Eau de toilette and eau de parfum differ in concentration, not volume.

Can I bring a 5 oz bottle with only 15 mL left in a carry-on?
No. The limit reads the container size, and a 5 oz bottle is over 3.4 oz whatever is left in it. Move the 15 mL into an atomizer marked in mL, and check that it is under the limit.

No. Eau de toilette and eau de parfum differ in how much fragrance oil they hold. A 50 mL bottle is 50 mL in either.
