Do you use an apostrophe or comma for numbers?

Question

For example, is it 5'000 or 5,000?
I use the apostrophe but most people I know use commas...why is this?

Answer 1

A comma is the correct way. I have never seen an apostrophe used for this.

Answer 2

Definitely a comma for numbers, usually separating thousands. This is to enable the human eye to separate blocks of 3 places more easily e.g. 1,234,567, as opposed to 1234567. A decimal point is normally used to separate units from tenths e.g. 25.67 for 27 and 67 hundredths.

When writing units of measurement such as feet and inches, or degrees of angle, the symbol used as a separator is not a comma, which has a specific curly shape, but a single or double superscript dash, e.g. 5' 6'' for 5 feet 6 inches, or 27' 36'' for 27 degrees 36 minutes of arc When a comma symbol is used in the superscript position, it is known as an apostrophe, and is used to indicate either possession or an abbreviation. It is probably the most misunderstood and misused symbol in written language. It is possible to put a comma in the superscript in a word processor, but it is generally acceptable to use the superscript dash (') instead, when using the kind of editor normally available for emails and for answering question here

Answer 3

Does your teacher use an apostrophe?—because I've NEVER seen it used that way.



Marlon is incorrect. In the U.S., a comma is used to separate digits and a period is a decimal point.

In some other countries it's the exact opposite.

Answer 4

Use a comma for a large number to separate tens, hundreds and thousands - this helps if a number has to be read out, e.g. 100,000 is one hundred thousand in words.

An apostrophe may be use after a number to replace 'feet' and 'inches', e.g. 5 feet and 2 inches could be written as 5' 2".

Answer 5

Yeah, comma is the right way, also I saw that in US they use dot like 5.000
