Units
The Units used for a RocPlane 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.
