Rightwards Arrow From Bar Symbol
The ↦ symbol indicates a mapping or assignment from one element to another.
U+21A6
↦ is a Unicode arrow known as the Rightwards Arrow From Bar. It’s commonly used to express “maps to” or “is mapped to” in text and diagrams. Use it when you want a clear, compact mapping arrow.
Rightwards Arrow From Bar Symbol Meaning
The Rightwards Arrow From Bar (↦) is primarily used to show mapping or association from a source to a result. You’ll often see it in contexts where something is transformed or defined in terms of another value—similar to “maps to” in mathematical writing or technical documentation. In UI copy or explanatory text, it can suggest that an input corresponds to an output, action, or rule. Because it’s a distinct arrow glyph, it helps communicate “from … to …” relationships more precisely than a generic arrow in dense content like specifications, notes, or interface labels.
Common uses
- •Math and logic notes to write “maps to” relationships
- •Documentation to indicate how an input is transformed into an output
- •Flowcharts and diagrams where a definition or rule produces a result
- •Code-related writing (comments/specs) to describe mapping rules
- •UI microcopy to label “input → action/result” in forms or settings
