5.5 feet = 1.68 metres. NB: 5.5 feet is 5 ft 6 inches, not 5 ft 5 inches.

Based on the NPS and schedule of a pipe, the pipe outside diameter (OD) and wall thickness can be obtained from reference tables such as those below, which are based on ASME standards B36.10M and B36.19M. For example, NPS 14 Sch 40 has an OD of 14 inches and a wall thickness of 0.437 inches. However the NPS and OD values are not always equal, which can create confusion.For NPS â…› to 12 inches, the NPS and OD values are different. For example, the OD of an NPS 12 pipe is actually 12.75 inches. To find the actual OD for each NPS value, refer to the tables below. (Note that for tubing, the size is always the actual OD.)For NPS 14 inches and up, the NPS and OD values are equal. In other words, an NPS 14 pipe is actually 14 inches OD.The reason for the discrepancy for NPS â…› to 12 inches is that these NPS values were originally set to give the same insidediameter (ID) based on wall thicknesses standard at the time. However, as the set of available wall thicknesses evolved, the ID changed and NPS became only indirectly related to ID and OD.For a given NPS, the OD stays fixed and the wall thickness increases with schedule. For a given schedule, the OD increases with NPS while the wall thickness stays constant or increases. Using equations and rules in ASME B31.3 Process Piping, it can be shown that pressure rating decreases with increasing NPS and constant schedule.[note 1]
NB is nominal bore of that pipe, that doesn't mean that the pipe diameter (Inner or Outer)will be equal to the NB, but it is an digit nearest to the out side diameter of the pipe. That digit will be an easily memorable one like 25, 20, 32, 40 etc (Not like 23.25, 27.5, 41.8 etc). In standard pipes, the NB and the outside diameter will be same from 14 inches and above...
"nb" is not a recognised unit of measurement for length and so the question cannot be answered.
the inner diameter of the pipe Nominal bore (NB) is 40 mm

I am not quite sure what you mean by "nb", but I don't think it's a unit of length.

9 feet squared = 9 ft x 9 ft = 108 inches x 108 inches = 108 inches squared [= 11664 square inches]. NB: 9 feet squared is NOT 9 square feet.
