## Abstract

Selection of Units of measurement are important in many contexts, one of them is Key Performance Indicators (KPI). The selection can be aided by leveraging their dimensionality, additional data that describes the nature of a unit of measurement in a physical sense. In this way, a user can use the dimensional aspects to reduce the amount of presented options.

Using Dimensional Analysis Based UI to aid Unit Of Measurement selection

A program is disclosed whereby a user can utilise a UI to enter dimensional data which will be the basis for a set of options that will be presented. The user can thus approach the decision of selecting a useful and meaningful unit of measurement by the meaning which underlies it.

A typical embodiment would be the UI of a KPI program in which the user wishes to combine measurements in a mathematical fashion to create a KPI. Using the idea disclosed here, the user would begin by selecting the dimensions and combining them using operators or functions. The combination through operators and functions results in a relationship between dimensions that can be used to determine suited units of measurement.

A GUI embodiment could look like follows:

In the figure you see on top the basic dimensions, the ones depicted relate to the physical domain, but could be expanded to have units such as currency or other dimensions that make sense in a domain (for the physical dimensions, see for example: http://en.wikipedia.org/wiki/Dimensional_analysis). The idea behind this is that any measure can be broken down to these dimensions (e.g. Speed is Length/Time, Energy can be reduced to different types, such as length*mass (potential energy) or temperature*mass (thermal energy)).

The UI allows them to be dragged and dropped into the formula below (example is for a simple formula containing only divisor and divid...
