# Unit & Unit Conversions

See also the configuration page.

The data units are the smallest unit of measurement of any time series. MDA will store the data in this unit as a 64 bit signed long value.

The display units are shown to the user and sent to HWE, via MDA-API etc.

The import unit is used to interpret the data given to the SCADA importer. It will be converted into data units.

For calculations the values are converted into the set unit from the formula reference; the resulting value is interpreted as the display unit of the formula time series and converted into its data units.


The user is responsible for correct transformation data between one unit to the other. Additionally, make sure that the data unit has always a conversion into the display unit and back.
