Spell out zero through nine. Use the numerals for numbers greater than nine.
For example: Durham College will welcome seven new full-time faculty members this September and 12 part-time professors.
When one million is reached, numbers should read one million, two million, etc., not 1,000,000. Also, round off seven-digit or greater numbers wherever possible. However, if the number requires a decimal point, the numeral should be used in place of the word.
For example: The GTA is home to 6.2 million people (not 6,200,500, 6.25 million, nor six-point-two million).
Exception: When writing about money, use the numeral.
For example: BMO Financial Group donated $1 million in 2004 to help establish Durham College's Campus Library.
Spell out any number that begins a sentence.
For example: Forty-three Durham College students took part in the fundraising walk.
Use commas with all numbers above 999.
For example: There were 1,000 students at the event.
Reference the first, second, third, etc. up to the ninth, except in the case of dates.
Over 10 should be written as 10th, 11th, 12th, etc.
Use numerals when referencing grades, days, room numbers, years, and capitalize the word.
For example: Many Grade 12 students will begin applying to college this fall.
