About the Approximately Symbol
The approximately equal symbol (≈), called “almost equal to” in Unicode (U+2248), is used in mathematics and science to indicate that two values are close but not exactly equal. For example, π ≈ 3.14159 or √2 ≈ 1.414. It is commonly used in estimation, rounding, and physics equations. The symbol consists of two wavy tildes stacked vertically. Related symbols include the single tilde (∼, U+223C) meaning “similar to”, the asymptotically equal sign (≃, U+2243), and the approximately-equal-or-image-of sign (≊, U+224A). On keyboards the tilde (~) is often used as an informal approximation symbol. You can copy the exactly correct Unicode symbol from this page or use the HTML, CSS, or Alt codes provided.

Approximately Symbol One Line Meaning
The one-line approximation style is commonly written using:
| Symbol | Meaning |
|---|---|
| ~ | Approximately or around |
Difference Between ~ and ≈
| Symbol | Usage |
|---|---|
| ~ | Informal approximation |
| ≈ | Mathematical approximation |
Example
| Informal | Formal |
|---|---|
| ~10 minutes | 10 ≈ 10.2 |
The ≈ symbol is more mathematically accurate.
Approximately Symbol Example
Practical examples help explain approximation usage clearly.
Example 1
\frac{22}{7}\approx3.14
Example 2
