Numbers and measurements

Style for numbers and measurements supports accessibility and readability for users.

Generally write numerals for 2 and above. Note the few exceptions to the general rule of writing numbers as numerals.

Use words for ordinal numbers up to ‘ninth’ and for fractions.

Write mathematical relationships and operations as words, unless the symbols help the user. Use symbols for currency and percentages in most cases.

Put non-breaking spaces in telephone numbers.
