How do we translate 1210 into words:

1) one thousand, two hundred, and ten

2) one thousand, two hundred and ten

or without the commas

3) one thousand two hundred and ten

4) one thousand two hundred, and ten ?

In the UK, we always put the "and" in after the hundreds in plain numbers. Commas appear to be put after every "power of 1000" term ("thousand", "million", "billion" and so on); I'm not sure whether that's a requirement or just a good idea. However, not even the most knee-jerk believer in Oxford Commas would put a comma after the hundreds. So it is:

One thousand, two hundred and ten.

In the US, they seem to always leave the "and" out, but use commas in the same way:

One thousand, two hundred ten.

There is another alternative, though. With a number like this between one and two thousand, in the UK at least we might still talk about it hundreds:

Twelve hundred and ten.

This is very much dependent on context and personal preference, but it does happen so you shouldn't be surprised by it.

  • +1 -- the use of and after the hundreds is a regional thing. In Canada, the use of and is commoner than the and-less American variant (though that's likely to change in a generation or two due to cultural influences from our neighbour). – bye Jul 08 '11 at 16:30
  • I was taught the "and"-less American style in elementary school, and later on in my education I was told that it came from finance; when writing a check, the only "and" in the amount as spelled out should come between the whole dollar number and the fractional cent value: "One thousand two hundred ten and no/100". This is mainly to prevent a forger from adding more dollars to a big round number; if "and" is seen in the middle of such a number, it is suspect. Also, the word "Dollars" is usually preprinted at the end of the line and thus can't be used to differentiate between dollars and cents. – KeithS Jul 08 '11 at 16:36

    @KeithS: Wouldn't it be suspicious to see anything after "two hundred (and) ten" in either case? I suppose "thousand" could come after that, but that's not a big concern with my bank balance :) In the UK the convention is to use "only" to avoid additions at the end: "two hundred pounds only". – psmears Jul 08 '11 at 17:06

    Good answer, though outside the scope of the question its possibly worth mentioning the and will crop up again when we reach 101,000 (one hundred and one thousand). Its used every time we have more than a hundred of a major unit, i.e. 111,222,333 (one hundred and eleven million, two hundred and twenty two thousand, three hundred and thirty three) – Robb Jul 13 '11 at 10:55

It depends on where you live. I live in the US, and the following is what I'm used to:

One thousand, two hundred ten

This is the only way I've heard to be correct. There isn't an "and" between "two hundred" and "ten", when you are writing, and usually commas come after "thousand", "million", "billion", etc; never after "hundred".

"One thousand, two hundred ten". The use of "and" in a number without a decimal can be confusing, especially in the context of money: does "One thousand, two hundred and ten" mean $1210 or $1200.10? Accountants have lost their jobs over smaller differences.

The comma can also be dropped in situations where it too may be confusing; in a list of numbers, for example. "One thousand two hundred ten" is perfectly unambiguous and punctuationally acceptable.

  • Is punctuationally really a word? I'm a bit skeptical. :-) – Kit Z. Fox Jul 08 '11 at 15:23
  • The thought behind the word was apparently communicated, so whether it's in the OED or not it did its job :-) – KeithS Jul 08 '11 at 16:03

    We get by just fine in the UK always using "and" in numbers, and no such confusion results. And indeed the ambiguity is still there even without the "and" :-) – psmears Jul 08 '11 at 17:12
  • @Kit you shouldn't be. download Google Dictionary plugin. all it takes is a double click, i get "No definition" – Pacerier Jul 29 '11 at 16:57
  • @psmears Are you saying that the decimal separator is read ‘and’ in the U.S. and ‘point’ in the U.K.? So 101.10 is read ‘one hundred one and ten’ in the U.S. while it is read ‘one hundred and one point ten’ in the U.K.? – Géry Ogam Mar 25 '20 at 11:01
  • @Maggyero: No, I'm not saying that. In the UK, 1210 is usually "one thousand, two hundred and ten". Some dialects (commonly in the US) omit the and. "One hundred fifty" could mean "One hundred [pounds] fifty" i.e. £100.50, or "One hundred and fifty", i.e. 150. So omitting "and" doesn't remove any ambiguity. – psmears Mar 28 '20 at 01:39
