Numbers

Less than 10 and at the beginning of a sentence, use words: one, three, five, seven, nine. From 10 upwards, use numerals unless the number is the first word in a sentence, e.g.: Eleven men walked down the road.

Exceptions, such as semester 1 and World War II, are as shown in Dates, events and periods

Percentages are typically expressed as:

  • 3%
  • 9%
  • 98%.

If spelt in full, percentages are expressed as 'per cent', not 'percent', e.g. 3 per cent.

Where large numbers are shown in tables, use a typed space to separate millions and thousands:

  • 122 456
  • 23 500
  • 3 450
  • 6 300 000.

Elsewhere, use commas:

  • 3,000 years
  • 22,000 years
  • $5,000
  • $36,000
  • $2,500,000.

In narrative it is often more elegant to express millions or thousands in words, e.g. 'a $2.4 million budget'

Also refer to Phone numbers.


Currency

  • A$100 (use only where there could be confusion)
  • NZ$5000
  • US$6000.
