Document Summary
Distance between two points on a specified path. Each dimension is a property of the physical quantity with the same name. Rate of spontaneous conversion of future to past: not necessarily a property unique to that quantity. The quantity mass refers to an amount of matter. The dimension mass is more general and is a property of anything that can be measured on the same scale (or with the same units) as mass. Each can be measured in a proper quantitative fashion: each has a real zero-point, none can be explained in terms of the other two. Neither physical quantities nor dimensions are synonymous with units. The dimensions of a quantity constitute the scale on which we measure it: the units are the rather more specific matter of how we mark or subdivide that score. The names of units often reveal the underlying dimensions.
