abbreviations: imperial system

Abbreviations for imperial weights and measures take the same form for singular and plural.

  • 17 in. (inches)
  • 1 ft. (foot)
  • 38 yd. (yards)
  • 1 mi. (mile)
  • 55 mph (miles per hour)
  • 4 oz. (ounces)
  • 69 lb. (pounds)
  • 1 pt. (pint)
  • 3 qt. (quarts)
  • 4 gal. (gallons)

With this system, area and volume are usually expressed by means of the abbreviations sq. and cu. rather than a superscript numeral. Leave a space between sq. or cu. and the abbreviation that follows it:

  • 100 sq. ft.
  • 20 cu. yd.
