Kelvin Sign Letter
The Kelvin Sign K (Unicode U+212A) is a typographic symbol for the kelvin temperature unit.
U+212A
K is known as the Kelvin Sign. It’s a specific Unicode character (U+212A) you can use in design, writing, and web content. Copy it directly or use the provided escapes in code.
Kelvin Sign Letter Meaning
The Kelvin Sign K represents the kelvin, the SI unit of temperature. In everyday text, temperatures measured in kelvins are written with the letter K (for example, “300 K”), but K is a dedicated typographic character that visually distinguishes the symbol. Because it’s a distinct Unicode character (U+212A, HTML entity K), it can be more consistent in layouts that rely on specific symbol styling. Use K when you want the dedicated Kelvin glyph rather than a plain “K”, such as in posters, scientific headings, UI labels, or product documentation.
Common uses
- •Scientific labels and temperature readings in documents and dashboards
- •Designing typography for charts, graphs, and data visualizations
- •UI and app text for settings, calibration values, or sensor readouts
- •Educational materials explaining temperature units and units conversion
- •Math/science social media posts where a distinct kelvin glyph is preferred
