On Tuesday my daughter and I were in Jersey Channel Islands for a pre-wedding bonding session.(Big Day-10th July)
I am making her wedding cake which requires vast numbers of passion fruit. We saw a shop selling passion fruit puree which we've never seen anywhere else. We bought four small cylindrical tins.
An hour later I realised that we were travelling hand baggage only and these tins were more than 100mls.We returned to the shop and swopped them for 4 smaller tins- each 110 grams .Being a child of Imperial Measures I spent some time calculating and concluding that each held less than 100mls. We duly swopped around our make up and toiletries in the hotel and fitted them tidily into the bag.
At the airport we sat in Starbucks right opposite the poster reminding us of the 100mls regulation and the size of bag.
We were pulled in at security and they told us it was 100mls or 100grams. We tried to no avail to argue the toss and eventually I was escorted back to post them. In the meantime they had searched my daughters bag and found a cheese which she had bought as a present.-you've guessed it- liquid! Argued that too.
So I posted two parcels to the U.K.
This morning less than 48 hours later they arrived with the cheese in good condition. I thought I would tell you -until I read the "directgov " which only mentions 100mls no mention of grams!.........

100mls of water weighs 100grams. Puree would be denser I'd imagine so weigh more for less volume.
However they are using the water rule for carry-ons.
Glad it all arrived safely!

IIRC, the density of water at 4 C is 1 g/cc, not 1 g/ml.

That is why 1 L of water is 1.05 US quarts instead of 1.0.

Unfortunately, F, your little cans still come out above 100 ml.

You have my sympathy, btw.
One time I put the carryon that had all of my wife's paraphernalia into checked luggage and brought the carryon with the wine, foie gras, etc with me.

I watched while the agent opened the bottles and tins to make sure that there would be no party later.

1cc = 1ml = 1gm

that's the link between linear measure(cm), liquid (ml), and weight (gm), by definition

and density has nothing to with the ratio of L/qt.

I see that you are converting to mls from weight BUT the point which caught me out was that the security men said that the limit was an alternative of either 100mls(which I knew about) or 100 grams(which I didn't.) None of them said that I was over because 110grams converted to a figure in excess of 100mls. They said it was quite well publicised that it was either /or.
I haven't opened the tins yet but they don't appear to have more than 100mls in them

I have now opened and measured the contents of these tins and they are marginally less than 100mls each

Hi F,

I had 3 tins of pate confiscated because they weighed 110 g ea.
