Per Mille Sign ‰

The Per Mille Sign character (‰) is a standard HTML entity defined in the HTML specification. In HTML source code, it can be written using the named entity reference ‰, the decimal numeric character reference ‰, or the hexadecimal numeric reference ‰. The character is assigned Unicode code point U+2030 in the Universal Character Set.

The per mille sign (‰) means 'per thousand' and represents a ratio expressed in thousandths. It is analogous to the percent sign (%) but with a factor of ten greater precision. Per mille is commonly used in finance (interest rates), blood alcohol content measurements, salinity, and industrial quality metrics.

Symbol entities encompass a wide variety of special characters used in legal disclaimers, intellectual property notices, typographic ornaments, card suit indicators, and miscellaneous notation throughout web content. These characters appear in website footers for copyright notices, product pages for trademark symbols, academic papers for dagger footnote markers, and decorative or gaming contexts for card suits and stars.

When deciding how to encode the Per Mille Sign character in your HTML documents, the named entity ‰ is generally the most readable choice for developers reviewing or maintaining source code. The decimal form ‰ and hexadecimal form ‰ are equally valid alternatives that work in contexts where named entities may not be supported, or when generating HTML output programmatically from server-side code. All three representations produce identical visual output in every modern web browser.

Use the per mille sign in financial content (bond yields, interest rate spreads), blood alcohol concentration (0.08‰), salinity measurements, and precision engineering specifications. It provides finer granularity than percentages and is standard notation in several specialized fields.
