Variant Menu: Options > Site Data > Units

On the Units page, you can select a set of physical units for display or define units individually.

Proceed as follows:

• Click on Load TSOL Default* to use preset units that generally ensure a good representation.

OR:

• Select User defined and click Define Units to individually set the physical units.
  
  SI and US units can also be mixed.

OR:

• Select SI units: All units are displayed in the official SI system. Individual values may be displayed as very large or very small numbers.

OR:

• Select US units: All units are displayed in US units. This applies to linear measurements, temperatures, and energy units.

TSOL saves the selected units separately for every user in C:\<User>\<UserFiles>\Valentin EnergieSoftware\TSOL\6.0\units\einheiten.txt. If this file has inadvertently become corrupted, you can simply load the original values by clicking Options > Units > Load TSOL Default.

The units used are divided into the following groups:
