pesature

Pesature is the act or process of determining the mass or weight of an object, typically by comparing it with a reference standard. The term originates from the Italian pesare, to weigh, and pesatura, the act of weighing; in practice, pesature encompasses procedures, instruments, and results used to quantify mass in laboratory, industrial, and commercial settings.

Mass versus weight: In metrology, pesature usually means measuring mass (the amount of matter), while weight refers to the gravitational force on that mass. Most weighing systems report mass in kilograms, though some contexts express weight in newtons or pounds. Measurements are made with instruments that translate a mechanical force into a readable value.

Instruments and methods: Classic balance scales compare an object against known masses; modern digital scales and analytical balances provide high precision. Other technologies include load cells and force sensors in weighing platforms, spring scales, and hydraulic or pneumatic balances. All instruments require calibration against primary standards and must maintain traceability to international definitions. Tare procedures and environmental controls (vibrations, temperature, humidity) are routinely used to improve accuracy and reduce bias.

Applications: Pesature is essential in commerce (pricing by weight), manufacturing and logistics (batching, dosing, shipping), agriculture, and pharmaceuticals. Legal metrology regimes regulate instrument accuracy, labeling, calibration intervals, and measurement uncertainty disclosures.

History and notes: The evolution from balance scales to electronic load-cell systems reflects advances in materials and electronics. Since 2019, the kilogram is defined by fundamental constants (Planck constant), reinforcing pesature by anchoring mass measurements to universal constants rather than a physical artifact.
