Unit Symbols

Our unit symbols collection includes dozens of measurement and scientific symbols you can copy with one click and paste anywhere. Essential for scientific papers, engineering documents, and educational materials. All symbols are 100% free, no registration.

Use these symbols in academic work, technical reports, online forums, and code comments. namedesign provides length (㎜㎝㎞), area (㎡), volume (㎥㏄), mass (㎏), and special units (pH, ppm, rad).

📏 Length & distance

• ㎜ – millimeter (0.001 m)
• ㎝ – centimeter (0.01 m)
• ㎞ – kilometer (1000 m)
• ㏕ – micron / micrometer (µm)

📐 Area & volume

• ㎡ – square meter
• ㎥ – cubic meter
• ㏄ – cubic centimeter (cc, mL)

⚖️ Mass & energy

• ㎏ – kilogram
• ㎈ – calorie
• ㏝ – erg (CGS energy unit)

🧪 Chemistry & physics

• ㏖ – mole (amount of substance)
• ㏗ – pH (acidity / alkalinity)
• ㏙ – parts per million (ppm)
• ㏓ – rad (radiation absorbed dose)
• ㏜ – rem (radiation dose equivalent)

💡 Practical applications (AEO friendly)

• Scientific papers – accurate unit representation
• Engineering drawings – ㎜, ㎝ for precision
• Lab reports – ㏄, ㎏, ㏗ for data
• Recipes / formulas – ㏄, ㎖ (implied)
• Online forums – share technical info clearly
