Introduction

Unicode Math Exponents — How They Work

Mathematical exponents are traditionally written using superscript positioning — x² means x to the power of 2. In plain text environments, reproducing this correctly requires Unicode superscript characters: ²(U+00B2), ³(U+00B3), ⁴–⁹(U+2074–U+2079). These are actual UTF-8 glyphs, not HTML formatting, so they display as superscript in any application that supports Unicode text.

This tool converts digit characters in your input to their Unicode superscript equivalents, letting you write proper math expressions (E=mc², a²+b²=c², f(x)=x³-3x²) in Google Docs, Discord, Instagram, Twitter, email, and any other platform — without needing LaTeX, HTML formatting, or word-processor menus.

How To

How to Generate Math Exponents

Type Your Expression

Enter your math expression using standard characters: "x2 + y2 = r2" or "E=mc2". Don't worry about formatting — just type the expression as you would on a keyboard.

Numbers Become Exponents

In real time, all digit characters convert to their Unicode superscript equivalents. x2 becomes x², E=mc2 becomes E=mc², a3+b3 becomes a³+b³. Non-digit characters stay unchanged.

Copy & Paste Anywhere

Click "Copy Math Expression" and paste into Google Docs, Discord, Instagram caption, email, GitHub README, or anywhere that accepts Unicode text. The exponents render correctly on all platforms.

⚡ Pro Tip

For scientific notation, type the full expression: "2.5 x 108 m/s" becomes "2.5 x 10⁸ m/s". For per-unit-area measurements, type "50 km2" for "50 km²". For negative exponents (x⁻²), type x-2 — the minus sign converts to superscript minus ⁻ automatically. See our main Superscript Generator for full alphabet superscript conversion.

Use Cases

When to Use Math Exponent Superscripts

📐

Geometry & Algebra

Write Pythagoras theorem (a²+b²=c²), area formulas (A=πr²), volume (V=⁴⁄₃πr³), and quadratic equations in plain text. Perfect for math teachers, students, and online tutoring content where LaTeX won't render.

⚡

Physics & Science

Express Einstein's mass-energy equation (E=mc²), Newton's inverse square law (F∝1/r²), and acceleration units (m/s²) in plain text emails, Discord, and social media. No LaTeX or image needed.

📏

Measurements & Units

Write area (m², km², cm², ft²), volume (m³, cm³, ft³), and other dimensional units with proper superscript. Essential for engineering documents, real estate listings, product specifications, and scientific papers.

💻

Code Comments & README Files

GitHub renders Unicode in README files and markdown. Use x², O(n²), and other exponent notation in algorithm complexity documentation, README math sections, and technical documentation without LaTeX plugins.

FAQ

Frequently Asked Questions

How do I type x² on a keyboard?+

Type 'x2' into this math exponents generator. The tool converts '2' to Unicode ² (U+00B2), giving you x². Click Copy and paste into Google Docs, Discord, email, or any text field. On Windows: Alt+0178 for ². On Mac: some apps support Option+2. The generator is the fastest method for any exponent.

What is the Unicode for superscript 2 (squared)?+

Superscript 2 (squared symbol) is Unicode U+00B2, named 'Superscript Two', in the Latin-1 Supplement block. UTF-8 encoding: C2 B2. Common uses: x² (x squared), m² (square meters), km², cm². Superscript 3 (cubed) is U+00B3.

Can I use math exponents in Google Docs without the Format menu?+

Yes. Generate your math expression with this tool (type x2+y2, copy x²+y²) and paste directly into Google Docs. Unicode superscript characters render correctly as exponents without Format → Text → Superscript or the keyboard shortcut Ctrl+Shift+=.

Does x² work in Discord, Instagram, and Twitter?+

Yes. Unicode superscript characters (², ³, ⁴, etc.) are standard UTF-8 glyphs that display correctly in Discord messages, Instagram captions, Twitter/X posts, and all major platforms. Generate your math expression and paste it directly into any social media text field.

What is the Unicode for x to the power n?+

For specific exponents: x² = U+00B2, x³ = U+00B3, x⁴–x⁹ = U+2074–U+2079. For general variable exponents like xⁿ, use superscript n = U+207F. For complex expressions, LaTeX notation (x^{n}) is recommended in formal mathematical typesetting. For plain text use, the Quick Insert buttons above cover all common cases.
