Why do some Americans say one fourth instead of a quarter?

Why do some people in the USA not use 'a quarter' and instead say 'one fourth'

A recipe might say one fourth of a cup - but I think they say 'one half' but not quarter

Sounds so odd to my ear

When I moved to China we were shown lots of houses to rent that had elaborate chandeliers, curtains with swags and tails, sofas with fringes …as that was an appropriate English style to make us feel at home. I explained we did not live in a national trust property and ikea style would be most welcome!

If I were teaching arithmetic to eight-year-olds I would expect them to learn that one quarter is exactly the same as one fourth and that two fourths are exactly the same as a half and that six times seven is exactly the same as six multiplied by seven et cetera, et cetera, et cetera.
When it's four o'clock in Italy the Italians say, "They are the four" or something very like it.

I'm a dual citizen, and have spent roughly half my life in each place and can't think of a time I've seen 'a fourth' in a recipe. It would usually be 1/4, which out loud would be one fourth.

And this is fine. If you haven't tried it, I recommend it.

I say a quarter cup and I'm from the Deep South. DH says one fourth; he's from New York State. I also say "quarter to" for time as do many Southerners.

Well, some of us DO drink tea from a china cup sometimes! Send'em round but give me time to get the packet of loose tea first.

I use both and I'm English.

The advantage of YYYY MM DD is when labelling electronic documents eg spreadsheets , they can be listed in date order in the file directory.

It's like a fortnight Vs 2w or a year Vs a twelve month. All commonly used in different parts of the UK.

They don’t, cos they call 25cent coins “a quarter”

OP is talking about measuring cups not money.
