Unit System
The Units used for an SWedge model are determined by selecting the unit of stress measurement under the General tab in the Project Settings dialog. You may select one of the following options:
- Metric units (stress) - MPa, kPa, tonnes/m2
- Imperial units (stress) - ksf, psf, tons/ft2
All input and output in the program will correspond to the selected stress measurement unit, as summarized in the table below.
Stress Units | Length | Force | Strength | Unit Weight |
Metric (stress as MPa) | meters | MN | MPa | MN/m3 |
Metric (stress as kPa) | meters | kN | kPa | kN/m3 |
Metric (stress as tonnes/m2) | meters | tonnes (1000 kg) | tonnes/m2 | tonnes/m3 |
Imperial (stress as tons/ft2) | feet | tons (2000 lbs) | tons/ft2 | tons/ft3 |
Imperial (stress as ksf) | feet | kips (1000 lbs) | ksf | kips/ft3 |
Imperial (stress as psf) | feet | lbs | psf | lbs/ft3 |
Default Units
Whenever the stress Units are changed in the Project Settings dialog, the currently selected units automatically become the default Unit selection for all NEW files.
