94 mm on a ruler is between 90 mm and 95 mm. On a typical ruler containing both mm and inches scales, where the scales are reversed with respect to each other, 94 mm is opposite 8 5/16 inches.

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...
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.

it is, probably, a pipe with nominal diameter (DN) 6 mm, and wall thickness 1.727 mm (SCHEDULE 40). See it here: http://en.wikipedia.org/wiki/Nominal_Pipe_Size
The internal diameter (ID) of a 32 NB (Nominal Bore) pipe is approximately 40.0 mm. Nominal Bore is a designation used to describe the size of the pipe, but the actual internal diameter can vary slightly depending on the pipe's schedule or wall thickness. For precise applications, it's essential to refer to the relevant standards or specifications for the specific type of pipe being used.
A 250 NP pipe is a pipe that is 250 millimeters in diameter and is 10 inches long. It comes in a variety of thicknesses. NB stands for nominal bore. Sometimes this is referred to as NPS which stands for nominal pipe size. NB is a standard for pipe sizes in North America.
The unit weight of a 60 NB (nominal bore) pipe depends on the material it is made from. For example, for a steel pipe with a nominal bore of 60 mm, the approximate unit weight can be calculated using the formula: Unit Weight = (outer diameter - thickness) x thickness x 0.024661.
