Unit & Measurement Symbols

Ohm, micro, angstrom, and the full set of scientific unit glyphs for physics, chemistry, and engineering. Click any symbol to copy it instantly.

Scientific and engineering writing relies on dedicated Unicode unit symbols that ordinary keyboards do not provide. This library gathers the electrical and physics signs such as the ohm (Ω), micro (µ), mho (℧), and angstrom (Å); the pre-composed metric squares from the CJK Compatibility block like ㎏ and ㎜; and the temperature and ratio marks used for measurements. Click any character to copy it for lab reports, datasheets, or technical posts.
