The American National Standards Institute ( ANSI ) is a private, not-for-profit, American organization that coordinates the development of voluntary standards in the United States. The non-profit organization is based in Washington, DC. The annual budget results from the sale of publications, membership fees, certification services, fee-based programs and international standardization projects.

It is the only US member in the International Organization for Standardization . The German equivalent is the German Institute for Standardization (DIN), the Austrian equivalent is the Austrian Standards Institute and the Swiss equivalent is the Swiss Association for Standardization .

Although the ANSI standards cover many areas, the abbreviation "ANSI" used alone in computer technology is sometimes used to denote a certain group of character sets based on ASCII ; there is no real ANSI standard for this, but the ANSI drafts were incorporated into the ISO 8859 standard .

The ANSI-SPARC architecture , also three-level architecture, can be used for databases ; it describes the basic definition of a database system. The programming language C was also standardized by ANSI and is therefore also known as " ANSI C ". The same applies to the database query language SQL, whose ANSI conformity can be a selection criterion.

The luminous flux of digital projectors is also measured in ANSI lumens .

In the area of film speed , since the 1940s an indication “in ASA” has generally referred to a film speed standardized by the predecessor organization; since 1987, indications “in ISO” according to ISO 5800 have been common.
