Frequently Asked Questions

How many fluid ounces are in 100 mL?

100 mL equals 3.38 fluid ounces. This is why the TSA 3.4 oz limit is often labeled as 100 mL on travel-size products.

Is a fluid ounce the same as a weight ounce?

No. Fluid ounces measure volume (how much space a liquid takes up), while ounces (oz) measure weight. For water, they're approximately equal, but for other liquids they differ based on density.
