Quantity
Quantity is a property that can exist as a multitude or magnitude. Quantities can be compared in terms of "more", "less", or "equal", or by assigning a numerical value in terms of a unit of measurement. Quantity is among the basic classes of things along with quality, substance, change, and relation. Some quantities are such by their inner nature (as number), while others are functioning as states (properties, dimensions, attributes) of things such as heavy and light, long and short, broad and narrow, small and great, or much and little.
Surveying
Surveying or land surveying is the technique, profession, and science of determining the terrestrial or three-dimensional positions of points and the distances and angles between them. A land surveying professional is called a land surveyor. These points are usually on the surface of the Earth, and they are often used to establish maps and boundaries for ownership, locations, such as building corners or the surface location of subsurface features, or other purposes required by government or civil law, such as property sales.

The mass is a matrix from which all traditional behavior toward works of art issues today in a new form. Quantity has been transmuted into quality. The greatly increased mass of participants has produced a change in the mode of participation.
Walter Benjamin, “The work of art in the age of mechanical reproduction” (1935), Illuminations (1968), p. 239
Quantity
That curious modern hypostatization “service” is often called in to substitute for the now incomprehensible doctrine of vocation. It tries to secure subordination by hypothesizing something larger than the self, which turns out, however, to be only a multitude of selfish selves. The familiar change from quality to quantity may again be noted; one serves not the higher part of the self (this entails hierarchy) … but merely consumer demand. And who admires those at the top of a hierarchy of consumption? Man as a consuming animal is thus seen to be not enough.
Richard Weaver, Ideas Have Consequences (Chicago: 1948), p. 77
