When you'll use this
- Converting a US beverage can or bottle size (like a 12 fl oz soda can) into milliliters for international comparison
- Checking a US skincare or perfume bottle's fl oz size against the ml sizing used almost everywhere else
- Working out the TSA carry-on liquid limit (3.4 fl oz) in the 100 ml figure most travelers actually recognize
- Converting a US cocktail recipe's fluid-ounce jigger measurements into ml for an international bar
- Converting a US supplement or liquid medicine bottle's fl oz volume into ml for a pharmacy abroad
Practical note
This page gets a lot of use around travel: airport security's well-known "3.4 fl oz" carry-on liquid limit converts to almost exactly 100 ml, which is why the rule is stated in round 100 ml terms everywhere outside the US but as the odd-looking "3.4 fl oz" domestically. It is equally useful for product comparisons — a US-sold shampoo bottle labeled "8 fl oz" converts to about 236.6 ml, letting a shopper compare its price-per-ml against an imported or travel-size bottle labeled only in milliliters.
Tips
- The famous TSA/airport security carry-on liquid rule is "3.4 fl oz," which is exactly the rounded equivalent of the international 100 ml limit — this page shows precisely how that number was derived.
- A standard US soda can is 12 fl oz, which converts to about 354.9 ml — noticeably larger than the common European 330 ml can size.
- Fluid ounces measure volume, not weight — don't confuse a "fl oz" liquid measurement with a plain "oz" weight measurement, which converts using a completely different factor.
