Concept help - Unit Of Measure
A Unit of Measure describes units (eg. metres, litres, seconds) which can be used to record a measurement. A Value Domain can link to a single Unit of Measure to describe the units used to measure the associated data which can be used when to finding or comparing similar data.
The units in which the values in a value domain are measured. Adding unit of measure information makes the value more meaningful, especially in instances where a concept can be measured using various units of measure. For example, length or distance may be measured in millimetres, centimetres, inches, metres, feet, kilometres or miles etc.
While units of measure are specifically related to value domains, they are impertive to the formation of well described data elements.
