What Does the ≈ Symbol Mean?
The approximately equal sign (≈), also known as the almost equal or asymptotic symbol, indicates that two values are close enough for practical calculations without being strictly equal. It is standardly used when rounding irrational numbers, decimals, or experimental measurements.
Real Numeric Examples
π ≈ 3.14159 π = 3.1415926535... rounded to 5 decimal places Because pi is an irrational number that never terminates, expressing it in 5 decimal places uses ≈ to denote rounding.
1/3 ≈ 0.333 1 ÷ 3 = 0.333333... rounded to three decimal digits The recurring fraction 1/3 cannot be represented finitely in base 10, so ≈ signifies an approximation.

Step-by-step instructions for Windows, Mac, Word, Google Docs, Excel, HTML, LaTeX, and mobile devices:
Windows
Hold Alt and type 247 on the numeric keypad. Alternatively, type 2248 in Word and press Alt + X.
Alt+247 Mac (macOS)
Press Option + X on a Mac keyboard to insert ≈ instantly.
Option + X Microsoft Word
Press Alt + = to enter the equation editor, type \approx and press Space. Or type 2248 then Alt + X.
\approx Google Docs
Go to Insert > Equation, type \approx, and hit Space. Or Insert > Special characters and search 'almost equal'.
\approx Excel / Spreadsheets
Use the formula =UNICHAR(8776) to output the character ≈ in Excel.
=UNICHAR(8776) HTML & Web
Use the HTML named entity ≈ or the decimal code ≈.
≈ LaTeX (Math Mode)
Write \approx in LaTeX math mode ($x \approx y$). For single tilde approximation, use \sim.
\approx Android & iPhone (iOS)
Copy ≈ from this page, or long-press the ~ or = key on compatible third-party keyboards.
≈ Commonly Confused With
Distinguish ≈ from visually similar mathematical glyphs and characters:
Tilde
vs ≈A single tilde (~, U+007E or \sim) indicates geometric similarity or asymptotic order of magnitude, whereas double tilde (≈, U+2248) specifies numeric approximation.
Explore in geometry symbolsCongruent To
vs ≈The congruence symbol (≅, U+2245) combines an equals sign with a tilde to state that two geometric figures have identical shape and size.
Explore in geometry symbolsNot Equal To
vs ≈The not equal symbol (≠) strictly rejects equality, whereas ≈ affirms that values are nearly identical within a tolerance.

Answers to common questions about typing, meaning, and syntax for ≈:
How do you type ≈ on Mac?
On macOS, press Option + X to type the approximately equal sign ≈ into any document or search bar.
What is the Alt code for ≈ in Windows?
The Windows Alt code for ≈ is Alt + 247. Hold down Alt, type 247 on your number pad, and release Alt.
What is the difference between ≈ and ~?
The double tilde ≈ (\approx) means 'approximately equal to' in numeric calculations. The single tilde ~ (\sim) means 'similar to' in geometry or 'distributed as' in statistics.
How do you write approximately equal in LaTeX?
In LaTeX math mode, write \approx (e.g., $x \approx 3.14$).
