Meter vs. Metre – Which is Correct?
The choice between meter and metre hinges entirely on geographical location. Meter is the standard spelling used in American English, referring to a unit of length, a measuring device, or a rhythmic pattern. Conversely, metre is the preferred spelling in British English and other Commonwealth nations for the exact same meanings. For American audiences, “meter” is the correct and expected form.
Meter or Metre – Which is Correct?
The distinction between “meter” and “metre” is a classic example of regional spelling variation between American English and British English. Both spellings are correct, but their usage depends on the specific dialect you are writing or speaking in. In the United States, “meter” is the accepted spelling for all applications: the unit of length (approximately 39.37 inches), a device that measures (like a parking meter or gas meter), and the rhythmic pattern in poetry or music. In the United Kingdom, Canada, Australia, and other Commonwealth countries, “metre” is used for all these same meanings.
The Best Trick to Remember the Difference
To easily remember which spelling to use, consider the regional association:
- America uses “er”: Think of “United States” and how both “United” and “States” end with a sound that rhymes with “er.” The “er” ending in “meter” aligns with American English.
- Europe (and Commonwealth) uses “re”: Think of “Europe” or “United Kingdom” and how these regions commonly use the “re” spelling for words like “centre,” “theatre,” and “litre.” The “re” ending in “metre” aligns with British English.
Simply put: if you’re writing for an American audience, use “meter.” If your audience is British or from a Commonwealth country, use “metre.”

Etymology of the word Meter
The word “meter” traces its origins back to the Greek word metron, meaning “a measure,” “something used to measure,” or “a poetic foot.” This Greek root influenced Latin (metrum) and Old French (metre), from which English adopted the term. The spelling divergence (‘-er’ vs. ‘-re’) developed later as a result of distinct orthographical conventions solidifying in American and British English during the 18th and 19th centuries, largely influenced by figures like Noah Webster in the United States.

Frequently Asked Questions
Question 1: Is “meter” always a unit of measurement?
No, while “meter” is famously the base unit of length in the metric system, it can also refer to a device that measures (e.g., a gas meter, parking meter) or the rhythmic pattern in poetry or music (e.g., iambic meter).
Question 2: Can “meter” be used as a verb?
Yes, “meter” can function as a verb, meaning to measure or regulate something with a meter. For example, “The utility company will meter your electricity usage.”
Question 3: Why do some words have both “er” and “re” endings in English?
The “er” and “re” endings, as seen in “meter/metre” or “center/centre,” are primarily a result of the divergence between American English and British English spelling conventions. American English often opted for simpler, more phonetic spellings, while British English tended to retain spellings closer to their French or Latin origins.
Conclusion

For American English speakers and writers, “meter” is the correct and expected spelling across all its meanings—as a unit of length, a measuring device, or a rhythmic pattern. Conversely, “metre” is the standard in British English and other Commonwealth nations. Understanding this regional difference is key to consistent and appropriate communication.
