Definition: Admeasurement refers to the measurement or estimation process that involves using known quantities, such as weights, distances, or volumes, to make a comparative judgment about an unknown quantity. This can involve comparing two different sets of measurements, such as two lengths from different sources. The term 'admeasurement' is derived from the Latin word "ad" meaning "with," and "measure," which refers to the process of determining what has been measured. The term 'admeasurement' is often used in a more scientific context when comparing quantities that are not directly comparable, such as measurements made on different scales or within different systems. In terms of its definition, 'admeasurement' typically involves a step-by-step approach where known quantities are compared to a target value, and the comparison results are analyzed to derive an estimate or judgment. The primary objective is to arrive at a precise measurement of some quantity by using known quantities and making comparisons.
