siWert

SIWert, sometimes written as SI-Wert, is a term used in German-language science and engineering to denote the value of a measured quantity expressed in the International System of Units (SI). The concept emphasizes that the numerical magnitude is provided together with its SI unit, facilitating direct comparison and interoperability between instruments and datasets.

It is typically applied in data sheets, measurement logs, laboratory reports, and automated data processing where standardization of units is required. The SIWert is not a separate unit or quantity; it is the conventional way of presenting a quantified result in SI units.

Important considerations include measurement uncertainty and significant figures. A SIWert value may be accompanied by an uncertainty interval or standard deviation, but the value itself represents only the central magnitude in SI units.

Examples: A length of 2.50 meters has SIWert 2.50 m. A temperature of 300.15 kelvin has SIWert 300.15 K. A mass of 12.7 kilograms has SIWert 12.7 kg.
