Units

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.
