Speaking of confusing the TSA, I wonder what they would do if confronted with stuff that is only labeled in metric units.

I have a bunch of stuff from a trip to Asia that is labeled in metric units only. I wonder how they are going to react to my 70ml bottles of shampoo, 9 gram tube of toothpaste, and 85 gram stick of gel deodorant. Something tells me they won't have any idea if they are 3 oz or less (all of them are though).

that would be 1 gram.. but a liquid with higher density would be heavier.

while 1 ml of mercury would be about 13.5 grams.

From my experience so far with the latest idiocy, they only care what the label on the container says.

I've been wondering what happens if you show up at a checkpoint with a large container of something that is, say, 13oz but where the leading "1" has been removed. My guess is that it'll sail right through.

They took a good long hard look at a bottle of ink that I had that was labeled only in metric. Then they let it through. 50 mL.

I hope that helps.
Thanks!! I will have explain something about toothpaste beyond the checkpoint. I will bring less 3oz next time when I am fly out from PHX.

FWIW there are about 28.3 grams (mL) to an ounce.

I just stopped by an McDonald's and saw a box of McFlurry mix outside. It was labeled in liquid ounces, so liquid ounces it is.
