measurementswhat

Measurementswhat is a coined term used in discussions of measurement design to denote the intended quantity or property that a measurement is meant to determine. In standard metrology, the corresponding concept is called the measurand; measurementswhat serves as a plain-language emphasis on the question "what is being measured?" rather than "how is it measured?"

Defining the measurementswhat clearly is essential for validity and comparability. Vague or incorrect specification of the measurand can lead to ambiguous results, misaligned instruments, and difficulties in aggregating data across studies or time periods. The distinction between the what and the how helps structure measurement plans, protocols, and reporting.

Examples illustrate the idea: measuring the length of a table, the measurementswhat is the table's length in meters; measuring the mass of a coin, the measurementswhat is its mass in grams; measuring task duration, the measurementswhat is the time taken to complete the task. The measurand is independent of the instrument or method used.

In practice, clear measurementswhat definitions support traceability, calibration decisions, and uncertainty analysis. They enable stakeholders to agree on targets, units, tolerances, and acceptance criteria. While measurementswhat is not a formal term in many standards, treating it as a planning concept can improve data quality and reproducibility.

Relation to related concepts includes measurand, instrument, measurement method, calibration, uncertainty, and data quality. See also: standardization efforts and metrology principles that describe how to define and manage the quantities being measured.
