Defines the following units for data items listed in the COMPONENT-INFORMATION-FILE (CIF):

The UNITS-DEFINITION section heading is followed by the identifiers and associated data listed below:
-
UNITS-BORE specifies inch or millimeter.
-
UNITS-LENGTH specifies foot (Weights/Foot) or meter (Weights/Meter).
-
UNITS-WEIGHT specifies kilograms (KGS) or pounds (LBS).

Input data formats
-
inch bores - You can type 1/2, 0.1/2, 0.5, 1, 1.0, 1.1/2, 1.5, 2, 10 (1 1/2 is also permitted for 1½)
-
mm bores - You can type 50 or 50.0
-
weights - You can type 25 or 25.0
Units selection process
It is expected that the units' settings in OS 41 and the FDF match. However, if they do not match, the sequence below is followed:
-
Units for weights and lengths - The units specified in OS 41 are regarded as the master units. For example, if OS 41 specifies weights in LBS, but the weights in the CIF are kgs, then all kilogram values are converted to pounds on output. A similar procedure is applied to length units.
-
Units for N.S. - The unit settings in the FDF and Piping data file must be the same. A check is performed between the N.S. units as defined by O.S. 41 and the UNITS-BORE attribute in the FDF. If they differ, the run is terminated with Error Code 35:1126.
