Numerals

This section provides style guidelines for the use of numerals in text that align with the ASU brand in addition to the latest AP style updates.

 

Amount vs. number

  • Amount refers to quantities measured in bulk or mass but considered as a whole.
    • βœ… Do: The amount of square feet in the classroom is enough to include a lab.
    • 🚫 Don't: She counted the amount of candies in the jar.
  • Number refers to things that can be counted individually.
    • βœ… Do: The number of books in the library grew in the last last year.
    • 🚫 Don't: The total number of square feet in the classroom includes a lab.
       

Numbers in copy

  • Spell out one through nine, except in headlines.
  • Use figures for 10 and greater, and for units of measurement and ages: 
    • βœ… Do: 3 mile.
    • βœ… Do: 18 years old
  • Spell out casual references: 
    • βœ… Do: ASU attracts thousands of international students each year.
    • βœ… Do: He walked a quarter of a mile.
  • Do not use both a word and numeric version of a number in a sentence: 
    • βœ… Do: Choose one of the sessions
    • 🚫 Don't: Choose one (1) of the classes
  • Beginning a sentence: 
    • Spell out a number at the beginning of a sentence except for calendar years
      • βœ… Do: Twenty people registered for the seminar.
      • βœ… Do: 1976 was a very good year.
    • A numeral-and-letter combination may start a sentence. 
      • βœ… Do: 3D movies are popular in the U.S.
      • βœ… Do: 401(k) plans are offered at the company.
         

Ages 

  • Always use figures, even for numbers less than 10: 
    • βœ… Do: She was 6 years old when she decided she wanted to be a Sun Devil.
       

Decimals

  • Use numerals and a decimal point when expressing all fractional values. 
  • For amounts less than one, add a zero before the decimal point and use the singular form of the measurement if singular: 
    • βœ… Do: 0.35 meter
    • βœ… Do: 0.55 cubic foot
    • βœ… Do: 0.75 kilometer
  • For grade point averages, include the hundredths place unless there are special circumstances: 
    • βœ… Do: 2.00 GPA
       

Dollars, cents, money

  • Use lowercase for denominations: dollar, cent, euro.
  • Do not hyphenate numerals and denominations.
    • 🚫 Don't: 2-million
    • 🚫 Don't: 10-cents
  • Cents: For amounts less than a dollar, spell out cents.
    • βœ… Do: 5 cents
    • 🚫 Don't: 5Β’
    • 🚫 Don't: $.05
  • Dollars: 
    • Use the dollar sign and the decimal system for amounts larger than a dollar
      • βœ… Do: $1.01
      • βœ… Do: $2.50
      • 🚫 Don't: 2 dollars

        Exceptions: Use the dollar sign with numerals in all cases except casual references of amounts without a numeral: about a hundred dollars.
    • For amounts less than $1 million, do not include decimal places: 
      • βœ… Do: $4
      • βœ… Do: $1,000
      • βœ… Do: $650,000
    • For amounts more than $1 million, use two decimal places if available: 
      • βœ… Do: Professor Jones was awarded a $4.35 million grant.
      • βœ… Do: He expended exactly $4,349,242 over the course of the grant.
      • βœ… Do: They proposed a $300 billion budget.
      • 🚫 Don't: $4.35M (except in tabular format), $300 Billion.
  • Euros: Do not use β‚¬ for euros, spell out: 
    • βœ… Do: 1,000 euros 
    • 🚫 Don't: €1,000
       

Fractions

  • Use figures for precise amounts larger than one, converting to decimals when possible. See Decimals.
  • In text: Spell out fractions less than one in text, using hyphens between the words: 
    • βœ… Do: Two-thirds
    • βœ… Do: Seven-sixteenths
  • In tabular formats: Use figures exclusively, converting to decimals if the amounts involve extensive use of fractions that cannot be expressed as a single character. See Decimals.
     

Grade levels

  • Use the numerals with an en dash and no spaces: 
    • βœ… Do: The program is designed for teachers in grades 7–12.

Note: To create an en dash: Mac β€” Option+Minus keys; PC β€” Ctrl+Alt+Minus keys. See Punctuation and symbols for en dash guidelines.

Measurements

  • Always use figures, even for numbers less than 10: 
    • βœ… Do: He lived just 3 miles from ASU’s West campus.
       

Ordinals

  •  Unless the ordinal is part of an official name or title: 
    • βœ… Do: Spell out first through ninth.
    • βœ… Do: Use figures for 10th and above.
  • Do not use superscript formatting. See Formatting for superscript guidelines.
     

Percent, percentage, percentage points

  • Use the % sign when paired with a numeral, with no space, in most cases: 
    • βœ… Do: The school’s enrollment increased 3.1% from a year ago.
    • βœ… Do: Nearly 14% were first-generation students.
  • Constructions with the % sign take a singular verb when standing alone or when a singular word follows an β€œof” construction: 
    • βœ… Do: Nearly 40% of the class was offered a chance to participate.
    • βœ… Do: The rancher reported 75% of the crop was harvested in September.
  • The % sign takes a plural verb when a plural word follows an β€œof” construction: 
    • βœ… Do: The rancher reported 75% of his trees were infested.
    • βœ… Do: Nearly 80% of the professor’s students participated.
  • Use whole numbers and decimals, not fractions, in percentages: 
    • βœ… Do: Nearly 10% of the crows migrated north.
    • βœ… Do: The increase in subscriptions was 13.25%.
    • 🚫 Don't: The increase in subscriptions was 13ΒΌ%.
  • For a range, the following are all acceptable
    • βœ… Do: 12% to 15%
    • βœ… Do: 12%–15% 
    • βœ… Do: between 12% and 15%
  • For amounts less than 1% precede the decimal with a zero: 
    • βœ… Do: The cost of living rose 0.6%.
  • Use percentage, rather than percent, when not paired with a number
    • βœ… Do: The percentage of people agreeing is small.
    • βœ… Do: A large percentage of the student body participated.
  • Be careful not to confuse percent with percentage point: 
    • A change from 10% to 13% is a rise of 3 percentage points. This is not equal to a 3% change; rather, it’s a 30% increase.
      • βœ… Do: Legislators passed a 0.25 percentage point tax cut.
      • 🚫 Don't: Legislators passed a 0.25 percentage points tax cut.
      • 🚫 Don't: Legislators passed a tax cut of 0.25 of a percentage point.
  • In casual uses, use words, not figures or numbers: 
    • βœ… Do: The latecomer had a zero percent chance of being first in line.
       

Phone numbers

  • Use only figures and hyphens
    • βœ… Do: 480-555-5555 
    • 🚫 Don't: (480) 555-5555
    • 🚫 Don't: 480/555-5555
    • 🚫 Don't: 480.965.5555
  • Always use an area code, but do not surround it with parentheses: 
    • βœ… Do: 480-555-5555 
    • 🚫 Don't: 555-5555
  • If an extension number is needed, separate it with a comma: 
    • βœ… Do: 480-555-5555, ext. 21

Ratios

  • Use figures and hyphens, no spaces between. Always include ratio or other noun with the figures.
    • βœ… Do: 22-to-1 student-to-faculty ratio
    • βœ… Do: A majority of 7-to-3

Temperature

  • Use figures for all except zero. Use a word, not a minus sign, to indicate temperatures below zero.
    • βœ… Do: The day's low was minus 10, 🚫 Don't: The day's low was -10. 
    • βœ… Do: The day's low was 10 below zero, 🚫 Don't: The day’s low was 10 below 0.
