Weighability
Weighability is a term used to describe the ability to determine an object's weight with a weighing instrument under specific environmental and instrumental conditions. In physics, weight is the force exerted on an object by gravity, while mass is a property of the object that remains the same regardless of location. Weighability thus depends on how accurately a scale or balance can translate that gravitational force into a readable value, taking into account factors that can distort or obscure the measurement.
Key factors influencing weighability include local gravity, air buoyancy, and the density of the surrounding environment.
Common weighing methods span balances that compare masses to reference standards and scales that measure force
