    • Ont.
    • P.E.I.
    • Que.
    • Sask.

    • An abbreviation has not yet been established for Nunavut, so it should be written out in all references

     *See Dalhousie mailing address for more information

Time zones

  • Use abbreviations for time zones with a clock reading:
     - 11 a.m MST or midnight Sunday night PST

  • Spell out time zones when they are not accompanied by a clock reading:
    - Newfoundland daylight time
  • Capitalize Newfoundland, Atlantic and Pacific time zones when spelled out. Other time zones are lowercase: eastern, mountain and central.


  • Celsius is abbreviated with a capital letter C, no period and one space between the temperature and abbreviation:
     - 35 C, -6 C
  • Do not insert any spaces if using the degree symbol:
     - 35°C, -6°C


  • Spell out numbers one through nine. For 10 and above, use numerals.
    Exceptions that always require numerals:
    • measurements that use abbreviations or symbols
    • percentages
    • combined whole numbers and fractions
    • currency
  • A number used to start a sentence is always spelled out

  • Percentages should always be expressed in numerals followed by "per cent."
    In text that includes numerous references to percentages, the symbol % is acceptable with no space between the number and the symbol.

  • For number ranges, use a hyphen between two numbers to indicate "up to and including" or "through." For number ranges preceded by "from" or "between," use "to" or "through" and "and" respectively:
     - The information is found on pages 123-154
     - from 1947 to 1949
     - between 100 and 150

  • Numbers with four or more digits: commas are used to separate three-digit groups except for house numbers, phone numbers, years and other serial numbers:
     - 1,000 not 1000; 3607 Charles Street

  • Avoid using too many zeros. Very large numbers can be written using a mix of numerals and spelled-out numbers:
     - 251.6 billion

  • School grades: Grade 7, but seventh grade


  • Use numerals to represent currency with the appropriate symbols. There is no space between the symbol and the numeral:
     - $8.99

  • Very large currency amounts can be written using a combination of numerals and words with the currency symbol:
     - $9.34 million, not $9.34 million dollars
