Established standard objects and events are used as units, and the process of measurement gives a number relating the item under study and the referenced unit of measurement. Measuring instruments, and formal test methods which define the instrument's use, are the means by which these relations of numbers are obtained.
The following objects are central in geometric measure theory: Hausdorff measure and Hausdorff dimension; Rectifiable sets (or Radon measures), which are sets with the least possible regularity required to admit approximate tangent spaces. Characterization of rectifiability through existence of approximate tangents, densities, projections, etc.
A unit of measurement, or unit of measure, is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. [1] Any other quantity of that kind can be expressed as a multiple of the unit of measurement. [2] For example, a length is a physical quantity.
