3 Terms and Definitions
3.1 Basic Concepts
112-01-01
Quantity quantity
Characteristic phenomenon object or substance, with a number and a reference to the object that best represents the size of this property.
[ISO /IEC GUIDE99.2007,1.1, MOD]
Note 1. The amount of general concepts can be divided into several layers particular concept, the table below, the left side of the table lists the "quantity" of specific concepts, they are also the right of the table
The general concept is more specific concepts.
Length, l
Radius, the radius r of the circle A, of rA is r or (A)
Wavelength, λ sodium D radiation, λD or λ (D; Na)
Energy, E
Kinetic energy, T given system kinetic energy of particle i, Ti
Heat, Q i is passed to heat water samples, Qi
Charge, Q the charge of a proton, e
Resistance, R the resistance of resistor i, Ri
Amount of substance concentration of the kind B, cB amount of substance concentration of ethanol in wine sample i, ci (C2H5OH)
Things number, N i a given number of turns of the coil, Ni
Rockwell C hardness (150kg payload), HRC (150kg) of steel sample i Rockwell C hardness, HRCi (150kg)
Note 2. The reference object may be a unit of measurement, measurement procedures, the standard substance (ISO /IEC GUIDE99.2007,5.13) or combinations thereof. Said the size of the amount
The "value" (see 112-01-28). In common with the unit of measurement of the case, the amount of size is a product of value and a unit of measure.
Note 3. The amount defined here is a scalar but vector (to) the amount or the tensor (whose components are the amount) is also considered to be the amount [see vector (102-03-21) and tensor (102-03-
