What Is the Superscript Two (²) Symbol?
The Superscript 2 (²) is a special Unicode character displayed slightly above the normal text baseline. It represents the number 2 written as an exponent and is most commonly used to indicate that a value is squared.
For example:
- 5² = 25
- x²
- a² + b² = c²
Unlike the regular number 2, the superscript version is smaller and positioned above the text. This makes it ideal for expressing mathematical notation, scientific formulas, references, and measurement units.

Why Is It Called Superscript Two?
The word superscript means a character written slightly above the normal line of text. Since this character represents the number 2 in superscript form, it is known as Superscript Two.
It is one of several superscript characters available in Unicode, alongside Superscript One (¹) and Superscript Three (³).
Difference Between 2 and ²
| 2 | ² |
| Standard number | Superscript character |
| Normal text size | Smaller and raised |
| Used for counting | Used for exponents and squared values |
| Regular numeral | Mathematical notation |
For example:
- 2 apples means two apples.
- 5² means five multiplied by itself (5 × 5 = 25).
Unicode Introduction
The Superscript Two symbol is assigned the Unicode value U+00B2. Unicode is an international character encoding standard that allows the symbol to display consistently across operating systems, browsers, applications, and devices.
Because it is a Unicode character, you can safely use ² in:
- Websites
- Documents
- Emails
- Mobile apps
- Programming projects
- Social media posts
Common Uses of the Superscript Two 2(²)

Although many people associate ² only with mathematics, it has several practical applications across different fields.
Mathematics (Squares and Exponents)
This is the most common use.
The superscript two indicates that a number or variable should be multiplied by itself.
Examples:
- 4² = 16
- x²
- y²
- (a + b)²
It frequently appears in:
- Algebra
- Geometry
- Trigonometry
- Calculus
- Statistics
Science and Physics
Scientists and physicists use ² in formulas involving squared values.
Examples include:
- Velocity calculations
- Acceleration equations
- Newton’s laws
- Energy formulas
- Scientific constants
You’ll often see expressions such as:
- m/s²
- r²
- c²
Units of Measurement (m², cm², km²)
One of the most familiar uses is for measuring area.
Examples:
| Unit | Meaning |
| m² | Square meter |
| cm² | Square centimeter |
| km² | Square kilometer |
| ft² | Square foot |
| in² | Square inch |
These units are commonly used in:
- Construction
- Architecture
- Real estate
- Interior design
- Land surveying
- Geography
Footnotes and References
Some publications use superscript numbers as reference markers.
Example:
The experiment was repeated²
The superscript directs readers to a note, citation, or additional explanation elsewhere in the document.
Although many citation styles use sequential superscript numbers, ² can also appear as part of that numbering system.
Chemistry and Engineering
In chemistry and engineering, superscript notation appears in equations, calculations, and technical documentation.
Examples include:
- Voltage equations
- Pressure formulas
- Engineering calculations
- Scientific reports
Note: Do not confuse the superscript ² with the subscript in chemical formulas such as CO₂. In CO₂, the 2 is written below the baseline to indicate two oxygen atoms, while ² is written above the baseline and usually represents an exponent.
Why the Superscript Two Symbol Is Important
The Superscript Two (²) symbol makes mathematical and scientific writing easier to read and understand. Instead of writing “raised to the power of two,” a single character communicates the same meaning clearly and professionally.
Whether you’re solving equations, measuring land, preparing academic documents, or creating web content, ² remains one of the most commonly used special characters in modern writing.
