For oven temperatures and weather, use 20C or spell out the word 'degrees' but do not use the little round degree symbol.


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.
