Writing out numbers - 1500 / 2500

[Lecword]

Hello everybody

I'd like to know how to write out these numbers. I've been told that numbers 1100-1900 can be written as "hundreds" but, is it the same with numbers bigger than 2000? What is the rule? Is it a British/American thing?

1500- one thousand and five hundred (British usage) or
one thousand five hundred (American usage) or
fifteen hundred :?:

1550- one thousand five hundred and fifty
one thousand five hundred fifty
fifteen hundred (and) fifty

2100- two thousand (and) one hundred
twenty one hundred

2185- two thousand one hundred (and) eighty five
twenty-one hundred (and) eighty-five


Would this be correct?

Thank you for your help

Yes, it's acceptable. Note that if you are reading "military time" (that is to say, the 24-hour clock), you typically omit "hundred" (unless it's on the hour) as well as "and". Here's an example:

1530 = Fifteen thirty
2000 = Twenty hundred
1355 = Thirteen fifty-five
1900 = Nineteen hundred
0900 = Zero nine hundred
0645 = Zero six forty-five

Note that in BrE, 1500 is "one thousand, five hundred". We don't put the "and" in there that you did.

"Fifteen hundred" is quite acceptable in AusE. It's used especially in lower numbers; 'Twenty-five hundred' is possible, but most people wouldn't go much above that, The context is important. If you're selling used cars, you might have three - one for 'nine hundred', one for 'nine fifty', and one for 'twelve hundred', or even 'twelve fifty'.
The most usual way of saying it is as emsr2d2 says above.

The same goes for AmE.
