Measures are numerical values that mathematical functions work on. For example, a sales revenue column is a measure because you can find out a total or average the data. Dimensions are qualitative and do not total a sum. For example, sales region, employee, location, or date are dimensions.

5 Answers. Usually, size connotes physical dimensions while magnitude connotes either a numerical measure (particularly a non-linear one) of any sort of amount or metaphorical size. You can also use size to mean metaphorical size, but you usually can't use magnitude alone to mean physical size.

Width or breadth usually refer to a shorter dimension when length is the longest one. ... Length is the measure of one spatial dimension, whereas area is a measure of two dimensions (length squared) and volume is a measure of three dimensions (length cubed).

Length= how long the thing is you're measuring. Width= how wide something is. ... If it is a rectangle, say a bookcase, then the height is how tall it is; length is the same as the height; depth is the measurement of the shelf from front to back; width is the measurement from side to side.

On the product page, the dimensions and unit of measure appear under the Specifications tab: ... Assembled dimensions are for descriptive purposes only and are used to inform customers about the assembled dimensions of a product. The difference between the two is easily demonstrated with flat pack furniture.

A dimension table consists mainly of descriptive attributes that are textual fields. When comparing the size of the two tables, a fact table is bigger than a dimensional table. In a comparison table, more dimensions are presented than the fact tables. In a fact table, less numbers of facts are observed.

A scale is virtually used for measurements along a straight line. A ruler need not be used for this purpose. The use of scale is simple in purpose whereas that of a ruler is complex in purpose. A ruler with straight edge is used with a little bit of an extra advantage than a scale.

to measure: to ascertain size by comparing with an object of known size; especially, by using an instrument or device marked in standard units. to estimate: to roughly calculate or judge the value of something. So yes, one of them is "obtained from reality" and the other is either "calculated" or "perceived".

Square meters and lineal meters measure two very different things. The measurement in square meters conveys an object's area, or the product of its length and width, in a single number. But lineal meters convey just one dimension, which could be length, width, height or anything else.

Measures and calculated columns both use DAX expressions. The difference is the context of evaluation. A measure is evaluated in the context of the cell evaluated in a report or in a DAX query, whereas a calculated column is computed at the row level within the table it belongs to.
