### 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\$5,000
• US\$6,000.
