enhetskode

Enhetskode is a code used in data systems to identify a unit of measurement or a unit type associated with a quantity. The concept is used to ensure that numerical values are interpreted consistently across records, datasets, and interfaces, facilitating accurate aggregation, comparison, and data exchange.

In practice, enhetskode appears in data fields such as unit_code or enhetskode within statistics, logistics, inventory, pricing, and health information systems. Codes are typically short alphanumeric strings, for example kg for kilogram, L for liter, m for meter, and stk or EA for stykk (piece). Many ecosystems also align with standardized code sets, such as the Unified Code for Units of Measure (UCUM) or other domain-specific lists, while some organizations maintain internal or project-specific vocabularies.

Implementation considerations include maintaining a controlled vocabulary of allowed codes, clear labeling, and validation rules to prevent invalid entries. Systems often support unit conversions (for example, converting grams to kilograms) to enable correct aggregation. It is important to handle locale-specific units, plural forms, and potential updates to the code sets over time, with proper mapping when standards evolve.

Relation to standards and practice varies by domain. UCUM and other standards provide machine-readable representations of units, aiding interoperability in cross-border or multi-system environments. In many organizations, enhetskode is part of a broader data dictionary or schema, ensuring that quantities are stored and interpreted consistently across applications.
