I’ve never heard it pronounced in my life, and despite being an Alton Brown fan, I just don’t remember it (and I think I would; it drives me crazy when he pronounces “greasy” as “greazy”). So another SDMB victory. I’ve always read “plantain” and imagined that it was pronounced thus. Many online dictionaries and Google prefer the “plantin” pronunciation.
And this is a good thing,™ as the rhyme is not true in America.
In Britain, where it rhymes (because a t is actually pronounced as a t and not a d), the rhyme is also true.
The American rhyme, because it falsely claims to be true everywhere, is not true anywhere
But it’s the vowels that fail to rhyme in American English.
In the UK, a pound is equal to 454 grams… But a pint is 568 ml!
Hence, a pound cannot be equal to a pint…
I wouldn’t worry about this too much because the Metric system is better and everything works out nicely with metric. In metric, 1g = 1ml, so 1kg = 1 litre etc. Much easier to work with. 
Hence, in my opinion, the Metric system is far better than the Imperial system and hopefully one day, the US will also convert to Metric. 
But it will take longer than four years (the age of this thread)
Wow, that’s some expensive water! How much is that in dollars?
It depends on the current exchange rate…
Ok, according to Google, £10 = $15.52.
No, because in American English, the ‘t’ is pronounced the same in both words.
The reason it rhymes in British English (of some ilks) is because the Brits don’t pronounce their r’s, thus “at” = “art”.
Yeah, I know it’s a zombie, but njtt is still around.
Next thing your’re going to tell me is a quart isn’t a liter. Or a litre, for that matter.
That’s like rounding pi to 3.
A US gallon is 128 liquid ounces, 231 cubic inches (by definition), 3785.4 ml. A gallon of water weighs 133.53 ounces, or about 8.35 pounds.
I never heard any but the plant-n pronunciation (vocalic n). I remembered reading once in a phonetics book the claim that in Philadelphia the 40th parallel (Lehigh Ave.) divides the people who say greasy to the north and greazy to the south. Well, I grew up south not only of Lehigh Ave., but of Market St. and never heard greazy in my life.
The same book claimed that l is given a lateral pronunciation everywhere in the English speaking world. Well, in my pronunciation, the initial l of lateral is lateral and the final l is not. So much for phonetics books.

Except in Baltimore (“Balmer” in the local patois.)
