Numbers

Write the numbers one to nine as words and use numerals after that.

Spell out first to ninth, then use 10th.

Use 1 to 9 when you’re talking about a stepped process or in a table.

Use numerals if the number is related to a unit of measure. For example 1km.

Don’t start a sentence with a number. If a number really must start a sentence, write it out in full.

     ✔  Thirty students attended the interstate sports carnival.

     X  30 students attended the interstate sports carnival.

Use a comma for numbers over 999 - eg: 9,000.

Spell out common fractions such as three-quarters or two-thirds.

Use a % sign for percentages - eg: 50%, not fifty per cent.
