Type any number, watch it square itself, and copy the exact ² symbol, superscript character, or squared equation you need — for math, science, units, and text.
Each square = 1 unit. The full grid is the area — that's what "squared" means.
Every superscript character you need for squaring, cubing, and exponents. Tap any tile to copy it instantly — no bulk block to pick apart.
The exact strings people search for most — algebra, physics, and area units.
Squaring a number means multiplying it by itself: n² = n × n. The small raised "2" is called superscript two or the squared symbol (Unicode U+00B2, HTML ²). It's used across algebra (x²), physics (E = mc²), and geometry, where it also describes area — a room that's 4m by 4m has an area of 16 square meters (m²), which is exactly what the grid above is showing you.
Squaring is different from square rooting, which asks "what number, multiplied by itself, gives me this?" — the reverse operation. See our square root vs. squared vs. cube guide if you need that instead.

| HTML | ² or ² |
| CSS content | content: "\00B2"; |
| LaTeX | ^{2} or x^2 |
| Word | Type 2, select it, press Ctrl+Shift+= (superscript toggle) |
| Google Sheets / Excel | Use ^2 in a formula, e.g. =3^2 → 9 |

² is called "superscript two." In everyday use it's just called the "squared symbol" because attaching it to a number or variable means that value is being squared (multiplied by itself).
On Windows, hold Alt and type 0178 on the numeric keypad. On Mac, press Option + 00B2. See the full keyboard table above for every device and app.
Unicode: U+00B2. HTML entity: ² or the numeric code ².
Yes. "n squared" and "n to the power of 2" both mean n × n. "Squared" is just the common name for exponent 2 specifically, the way "cubed" is the common name for exponent 3.
Use the caret operator: =3^2 returns 9. There's no dedicated superscript button in formulas, so ^2 is the standard way to square a value.
