enhetsneutralt

Enhetsneutralt is a term used in Swedish and Norwegian to describe something that does not depend on the choice of measurement unit. In practice, a quantity or formulation that is enhetsneutralt retains the same meaning when the unit system is changed; this is most directly true for dimensionless quantities or expressions that have been normalized.

Common examples are dimensionless quantities such as angles and probabilities, as well as ratios and normalized scores. The concept also applies when quantities are expressed in natural or non-SI units, or when a value is divided by a reference value to remove unit dependence, producing a unit-neutral form.

In science and mathematics, enhetsneutralt representations help facilitate comparisons across systems that use different unit conventions. A related idea is expressing relationships in a way that is invariant under scaling or unit changes, such as using dimensionless numbers or normalized variables. A limitation is that some intuitive information tied to specific units can be obscured, requiring additional explanation or context.

The term highlights a methodological preference for expressions that remain meaningful across unit systems, especially in cross-disciplinary research, international collaborations, and data analysis where unit consistency cannot be assumed.
