Usually we use words to write the numbers one to nine, and then use digits for the numbers 10 and above. We also use words when the number starts a sentence or comes after a bullet point.
- Four hundred people have registered for the conference.
- Five thousand Euros
In English, commas divide large numbers into groups. Decimal points are used for fractions.
- 1,500 (one thousand, five hundred)
- 1.5 (one point five, one and a half)
There are many ways to write dates in English. Spell out the date in full to remove any confusion. Use one of the following accepted formats:
- 10 April 2013
- April 10, 2013
Or, if you want to also include the day:
- Wednesday, 10 April 2013
- Wednesday, April 10, 2013
Remember, if you decide to use the format dd/mm/yy or dd/mm/yyyy for dates your reader could be confused about which date you are referring to. In US English the format is mm/dd/yy or mm/dd/yyyy. Spell out the date more fully to avoid confusion. It would be inconvenient to have a visitor arrive on 7 June when you’re expecting them to arrive on 6 July.

If you use the dollar sign ‘$’ make sure you specify which country’s currency you are referring to. Australia, New Zealand and Canada all use dollars, as do a number of other countries.
