The data input is not restricted to a specific system of units. In addition to the consistent units of user’s choice, four sets of system of units have been introduced in this version:
Unit = 0 => Consistent Units of User’s Choice
Unit = 1 => Consistent English Units (sec, in, Lbf, Lbf-s2/in)
Unit = 2 => Engineering English Units (sec, in, Lbf, Lbm)
Unit = 3 => Consistent SI Units (sec, m, N, kg)
Unit = 4 => Engineering Metric Units (sec, mm, N, kg)
For Unit=0, consistent units, it is essential that all of the input parameters be expresses in a consistent set of units of the user’s choice. For Unit=1 and 3, these are two sets of consistent units, however, their units will be displayed on the input screen and in the output text files. For Unit=2 and 4, these are two sets of units that are commonly used in the engineering field. Since they are not consistent units, their input units are explicitly specified on the input screen. Users must pay attention to their units.
The conversions between English and Metric units are list below for quick reference.
