mittetoetavaid

Mittetoetavaid is a Finnish term used in measurement science to denote the quantities or properties that are intended to be measured in a given process or experiment. In practice, the concept is closely aligned with what English-language texts refer to as measurands. The word combines mitta (to measure) with etava, roughly conveying “things that can be measured.” Despite this parallel, the term mittetoetavaid is not standard across all Finnish literature, and many texts prefer mitattavat suureet or mitattavat ominaisuudet.

Usage and scope

Mittetoetavaid refers to the set of variables for which measurement data are sought and that form the basis for measurement models, data analysis, and uncertainty assessment. Precisely identifying mittetoetavaid helps in selecting appropriate sensors or instruments, designing data collection protocols, and planning calibration and quality-control procedures. It also influences how measurement results are interpreted and reported.

Relation to other concepts

In metrology, mittetoetavaid is conceptually equivalent to measurands, though terminology varies by language and standardization body. When communicating with international audiences, it is common to use the standard term measurand or mitattava suure in Finnish and then clarify the equivalence to avoid ambiguity.

Examples

Typical mittetoetavaid include temperature, pressure, length, and mass in physical experiments. Derived quantities, such as velocity or concentration, may also be mittetoetavaid depending on the measurement objectives and the measurement model in use.
