Many people wonder whether to write gros or gross. The answer is simple: always use “gross” in modern English.
Confusing the two can make emails, reports, or social media posts look unprofessional. For example, writing “gros profit” instead of “gross profit” can confuse readers or reduce credibility.
This guide explains the difference, origin, and proper usage, with easy examples and tips so you can write confidently every time.
Gros or Gross – Quick Answer
Answer: The correct spelling is gross in modern English.
- Gross (with double “s”) is used in both American and British English.
- Gros (with a single “s”) is considered outdated or a French-influenced spelling.
Examples:
- Correct: The company made a gross profit of $5 million.
- Incorrect: The company made a gros profit of $5 million.
Quick tip: Always use gross unless writing in a context where French influence is required.
The Origin of Gros and Gross
The word gross comes from Middle English gros, borrowed from Old French gros, meaning “large” or “coarse.” Over time, English spelling conventions added an extra “s” to form gross.
- Old French “gros” → meaning big, large, or total.
- Middle English adoption → spelled as gros, used in manuscripts.
- Modern English standardization → doubled “s” to become gross for clarity.
This explains why you might see older texts or some European English use gros, but the accepted modern spelling in English is gross.
British English vs American English Spelling
Both British and American English use gross, but the spelling has slightly different historical influences.

| Usage in finance | gross | gross | gross margin |

Note: Using gros in modern writing is generally considered incorrect in both UK and US English.
