Approximately Equal Or Equal To Symbol
⩰ means “approximately equal to or equal to” in mathematical comparisons.
U+2A70
The symbol ⩰ represents an “approximately equal or equal to” relationship. It’s commonly used when a value should match within a tolerance, including exact equality. You can copy it directly or use the provided HTML/CSS/JavaScript escapes.
Approximately Equal Or Equal To Symbol Meaning
⩰ (U+2A70) is the “approximately equal or equal to” sign. Conceptually, it combines two ideas: approximate equality and exact equality. In mathematics and technical writing, it’s used when you want to express that two quantities are the same to a reasonable degree (for example, due to rounding, measurement tolerance, or numerical approximations). The symbol differs from a plain equals sign (which requires exact equality) and from strict “approximately equal” notations (which typically exclude exact equality). Use ⩰ when exact matches should also count as satisfying the comparison.
Common uses
- •Expressing that a measured value matches a theoretical value within an accepted tolerance
- •Comparing results in numerical methods where rounding error is expected
- •Writing equations or specifications that allow small deviations but still accept exact equality
- •Annotating graphs or data tables that show approximate agreement with a reference value
- •Communicating constraints in documentation (e.g., “≈ or =”) where exact equality is also valid
Examples
⩰ Approximately Equal Or Equal To
- ⩰x ⩰ y // x is approximately equal to or exactly equal to y
- ⩰T ⩰ 300 K based on calibration tolerance.
- ⩰p ⩰ 1.00 atm after rounding to two decimals.
- ⩰v ⩰ 9.81 m/s² for the measured range.
- ⩰The computed result r ⩰ the expected value within limits.

FAQ
What does ⩰ mean?
⩰ means “approximately equal to or equal to”, indicating approximate match including exact equality.
How do I copy ⩰?
Copy the character directly from this page. You can also use the HTML entity (⩰), CSS escape (\\2A70), or JavaScript escape (\\u{2A70}).
Is ⩰ the same as ≈?
Not exactly. ≈ typically indicates approximate equality, while ⩰ explicitly includes exact equality as well.
