3.1.1 Quantities and units

3.1.1.1 quantity A property of a phenomenon, object or substance whose magnitude can be represented by a number and a reference object. Note

1.Quantity may refer to the general concept of quantity or specific quantity. Note

2.The reference object can be a unit of measurement, measurement procedure, reference material or a combination thereof.

3.1.1.2 geometricalquantity The quantities of position, shape, and size in space in geometry.

3.1.1.3 Quantityvalue valueofaquantity The size of a quantity expressed as a number together with a reference object. Example. Length of given pole. 5.34m or 534cm.

3.1.1.4 The true value of the quantity truequantityvalue; truevalueofquantity truevalue truevalue A quantity that is consistent with the definition of quantity. Note

1.In describing the "error method" about the measurement, the true value is considered to be unique and is actually unknowable. In the "uncertainty method", it is considered that due to the The details of the definition itself are imperfect, and there is no single truth value, but only a set of truth values that are consistent with the definition. However, in principle and in practice, this set of values is unknowable. Other methods dispense with all notions of true value and rely on the notion of metrological compatibility of measurement results to assess the availability of measurement results. effectiveness. Note

2.In this special case of basic constants, the quantity is considered to have a single true value. Note

3.When the defined uncertainty of the measurand is negligible compared with other components of the measurement uncertainty, the measurand is considered to have a "substantially unique" true value. This is the method adopted by GUM (ISO /IEC Guide98-3.2008) and related documents (JJF1059.1-2012), where the word "true" is considered is redundant. 3.1.1.5
