Unit specification in XML file
The unit type is written to the XML Template by writing according to the Unit types table, eg. UnitType="Length^2/Force"
The unit definition for the specified unit type is written to the XML Template as a list of basic units separated by | , for example UnitDefMetric="m|kN" UnitDefImperial="in|kip"
The unit for certain data is written to the XML Data by taking text from the Unit Types table and adding an underscore and a specific unit to each base unit specification, eg. Unit="Force_kN*Length_m/Angle_rad/Length_m"
Units description
The currently used Unit System is specified in the task or in the stored data from the following options:
| Name | XML | Description |
|---|---|---|
| Metric | Metric
|
Metric unit system used elsewhere in the World except the USA |
| Imperial / English | Imperial
|
Imperial (English) unit system, inches, feet, pounds etc. |
Jednotka je určena typem jednotky (např. Force/Length^2) a skládá se z jedné či více základních jednotek (Force, Length). Speciální typ jednotky je Undefined, u něj se určuje popis jednotky uživatelsky.

Výjimky
Pokud je typ jednotky Force/Length^3, popis se upraví pro následující kombinace základních jednotek
| Force | Length | Popis |
|---|---|---|
| lbf | in | pci |
| lbf | ft | pcf |
| kip | in | kci |
| kip | ft | kcf |
Pokud je typ jednotky AltitudeLength, přidá se k popisu jednotky " n. m.", tedy např. "m n. m."
