Physical measure

• An unambiguous measure is a measure that reproduces a physical quantity of one size (for example, a weight of 1 kg )
• A multi-valued measure is a measure that reproduces a physical quantity of different sizes (for example, a line measure of length )
• A set of measures is a set of measures of different sizes of the same physical quantity (for example, a set of end measures of length)
• Measures store - a set of measures structurally integrated into a single device (for example, an electrical resistance store )
• Standard sample - a measure in the form of a substance by which the size of a physical quantity is reproduced as a property or as the composition of the substance from which the standard sample is made

Measures have been applied by man since ancient times, long before the appearance of the first measuring instruments; For a long time the concept of measure was associated with the concept of unit of physical quantity . As the first measures, parts of the human body were used, for example, the foot, elbow, and also other natural objects - grains, fruits. With the development of commodity relations, the transition to generally binding measures and their implementation in material form began, the first rulers , weights , etc. appeared.
