Input data, for example layer stiffness, strength or loads, are required to use eLamX². But as many other software eLamX² basically works independently of unit systems. The user must ensure that the data entered come from a common, consistent system of units, such as the SI or the imperial system of units. The following table shows some common consistent systems of units.
