Both “zeros” and “zeroes” are correct plural forms of “zero.” However, zeros is the more common and widely preferred spelling, especially in general and modern English.
People often wonder about these two forms because many English nouns ending in -o can take -es, while others take -s. “Zero” is one of the words where both forms are accepted.
In this guide, you will learn the difference between zeros and zeroes, how to use each one, where each form is common, and which spelling is safest for everyday writing.
Quick Answer
Zeros and zeroes are both correct plural forms of zero. Merriam-Webster lists zeros first and zeroes as another accepted plural.
- Zeros = the most common and generally preferred form.
- Zeroes = also correct, but less common.
- Both mean more than one zero (0).
Examples:
- The number has three zeros.
- The number has three zeroes.
For most writing, zeros is the simple choice.
Zeros vs Zeroes: Main Difference
| Word | Meaning | Correct? | Best Used For | Example |
| zeros | More than one zero | Yes | General, academic, technical, and everyday writing | The number contains four zeros. |
| zeroes | More than one zero | Yes | General writing when this spelling is preferred | She counted five zeroes. |
The two words have the same meaning. The difference is spelling, not definition.
Key Takeaway
If you are unsure which one to use, choose zeros. It is widely recognized and appears as the primary plural form in major dictionaries. Cambridge Dictionary also gives zeros as the plural in its main entry.
What Does “Zeros” Mean?
Zeros is the plural of zero. It refers to two or more instances of the number 0.
Zero can represent no quantity, a point on a scale, or the numerical symbol 0. In mathematics, it can also refer to a value that makes a mathematical expression equal to zero.
Examples
- The number 10,000 contains four zeros.
- Add two zeros to the end of the number.
- The calculator displayed several zeros.
- The student accidentally left out two zeros.
- The temperature dropped below zero, but the scale still showed several zeros elsewhere.
Zeros is especially useful when writing about numbers, mathematics, accounting, statistics, computer data, or everyday quantities.
What Does “Zeroes” Mean?
Zeroes has the same meaning as zeros. It is an accepted alternative plural spelling of zero.
For example:
- The account number contains six zeroes.
- She wrote three zeroes after the number.
- Count the zeroes carefully.
- The page contains several zeroes.
- There are too many zeroes in this figure.
There is no difference in meaning between zeros and zeroes when they are used as the plural noun.
Merriam-Webster specifically lists the plural as “zeros also zeroes,” confirming that both forms are established English plurals.
How to Use “Zeros or Zeroes”
The choice is mainly a matter of spelling preference.
Use “zeros” when you want the most straightforward form
Correct:
The number 5,000 has three zeros.
Use “zeroes” if that spelling fits your preferred style
Also correct:
The number 5,000 has three zeroes.
You do not need to change the meaning of the sentence. Simply choose one spelling and use it consistently.
A useful writing rule
For school assignments, professional documents, technical writing, and everyday communication, zeros is usually the safest choice because it is concise and widely accepted.
Do not confuse the plural with the verb
“Zeroes” can also appear as a verb form of zero:
She zeroes in on the main problem.
Here, zeroes does not mean multiple number symbols. It means focuses closely on something.
Merriam-Webster gives zeroes as a present-tense verb form of zero.
This creates an important distinction:
- Three zeros = three 0s.
- She zeroes in on the problem = she focuses on the problem.
Where to Use “Zeros or Zeroes”
Both forms can appear in many types of writing.
School Writing
Zeros is a natural choice in mathematics and academic work.
The answer contains two zeros.
Zeroes is not wrong, but zeros is often simpler.
Formal Writing
Use zeros when writing reports, instructions, or professional documents unless a particular style guide requires otherwise.
The system recorded three zeros in the data field.
Emails
Either spelling is grammatically correct.
Please check the zeros in the account number.
Everyday Conversation
People commonly use zeros.

Professional and Technical Communication
Zeros works well in finance, computing, mathematics, engineering, and data-related contexts.
The program removes leading zeros from the value.
American and British English
There is not a strict American-versus-British spelling rule that makes one form wrong.
Cambridge Dictionary gives zeros as the plural in its main English entry. Its American English information also recognizes zeros or zeroes.
Merriam-Webster likewise recognizes both forms.
So writers in the United States, United Kingdom, Canada, Australia, India, Pakistan, and other English-speaking regions may encounter both spellings.
Best practical choice: use zeros unless you have a reason to follow a style that prefers zeroes.
Why People Get Confused
The confusion comes largely from English plural rules.
Many nouns ending in -o can form plurals with -es:
- tomato → tomatoes
- potato → potatoes
- hero → heroes
But other words ending in -o simply take -s:
- photo → photos
- piano → pianos
- radio → radios
Zero is unusual because both zeros and zeroes are established forms. Merriam-Webster notes that nouns ending in -o have many exceptions and specifically includes zeros/zeroes among established plural forms.
This is why it is easy to assume that only zeroes can be correct. English spelling does not always follow one simple rule.
Common Mistakes to Avoid
Mistake 1: Saying “zeroes” is wrong
Wrong:
Zeroes is never correct.
Correct:
Zeroes is an accepted plural of zero.
Both zeros and zeroes are correct.
Mistake 2: Assuming “zeros” is incorrect because “tomatoes” uses -es
Wrong idea:
Every noun ending in -o must take -es.
Correct idea:
English has many exceptions, and “zero” accepts both forms.
Mistake 3: Using an apostrophe for the plural
Wrong:
The number has three zero’s.
Correct:
The number has three zeros.
An apostrophe is not normally used to make an ordinary noun plural.
Mistake 4: Confusing “zeroes” with “zeroes in”
Wrong assumption:
Zeroes in means several zeros.
Correct:
“Zeroes in” can mean focuses closely on something.
For example:
The report zeroes in on the main cause.
