What is a measurement?

A measurement is a quantification of a dimension, such as length or weight, usually represented as a number of standardized units. The type of measurement used depends on the properties being examined.

Measurements are useful because they help provide an accurate result in a number of situations. For example, to see whether a piece of furniture fits comfortably into a room, it may be necessary to measure the amount of space available in either centimeters or inches. Using a standardized scale is also important, as this helps people understand the dimension being represented and, if necessary, convert the number into a different metrical scale.
