Units
The Units of Measurement for RSData material models are specified in the Units section of the Project Settings dialog.
You may choose Metric or Imperial units, and the selection of Stress Units determines the units of length, force, stress and unit weight, for all program input and output as summarized below.
| Units | Length, Force, Stress, 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, tonnes/m2, tonnes/m3 |
| Imperial, stress as tons/ft2 | feet, short tons (2000 lbs), tons/ft2, tons/ft3 |
| Imperial, stress as ksf | feet, kips, ksf, kips/ft3 |
| Imperial, stress as psf | feet, lbs, psf, lbs/ft3 |
The Units should always be chosen at the start of modeling, since all program input is determined by the Units setting
