Usage notes[edit]

  • Whereas the spelling of the unit of length varies between British (metre) and American (meter) English, the spelling of this suffix is -meter in both. -metre is a nonstandard alternative form found in British English.
  • Words with the suffix -ometer always have a primary stress on the antepenultimate syllable: barometer, speedometer, tachometer, etc. Words derived from meter (or metre) with a prefix usually have a primary stress on the first syllable: centimeter, millimeter, etc.
