5.5 feet = 1.68 metres. NB: 5.5 feet is 5 ft 6 inches, not 5 ft 5 inches.
45.00...1 to 54.99... NB 45 would be rounded down to 40.
The thickness of 40mm NB MS Pipe is 4mm Regards, ZAFFAR EKBAL +91-9001798487
NO !!!! 600 cm = 6 m NB Remember there are 100 cm = 1 m
YES
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
The conversion factor to convert inches to "Nominal Bore" (NB) is 25.4 mm per inch. NB sizes are based on the internal diameter of a pipe, and they do not directly correlate to inches.
5.5 feet = 1.68 metres. NB: 5.5 feet is 5 ft 6 inches, not 5 ft 5 inches.
I am not quite sure what you mean by "nb", but I don't think it's a unit of length.

Formula for x-b=nB=84
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.
14" and above
NO!!! They are equal 0.0001 = 0.00010 NB the terminal zero is trivial .
