Using Unicode for the Degree Symbol
The degree symbol (°) is a crucial element in scientific, mathematical, and meteorological contexts, representing angles, temperatures, or other measured values. While many keyboards lack a dedicated degree symbol key, Unicode provides a universal solution. Here's a comprehensive guide on how to use Unicode for the degree symbol.
Understanding Unicode
Unicode is a computing industry standard for encoding, representing, and handling text in various languages and scripts. It assigns a unique code to every character, including special symbols like the degree symbol. By using Unicode, you can ensure consistent text display across different platforms and devices.
Unicode Code Points for Degree Symbol
The degree symbol has two Unicode code points:
- ° - U+00B0 (Degree Symbol)
- ′ - U+2032 (Prime) - often used as a shorthand for minutes in angles
How to Input Unicode Degree Symbol
