If you are bothering to measure it, it probably is not nominal data in your study.
Mean
The nominal size of a board is used to calculate board feet, not the actual size. Nominal dimensions refer to the board's rough-cut measurements, typically expressed in inches (e.g., 2x4), while the actual size is smaller due to milling (e.g., a 2x4 actually measures about 1.5x3.5 inches). To calculate board feet, you multiply the nominal dimensions and the length of the board in feet, using the formula: (Thickness in inches × Width in inches × Length in feet) / 12.
They are nominal.
Synonyms- length

The nominal length of wood refers to the standardized measurement used to describe lumber sizes before it is processed and finished. It is typically rounded to the nearest whole number, such as 2x4 or 2x6, but does not account for the actual dimensions after drying and planing, which are usually smaller. For example, a nominal 2x4 usually measures about 1.5 inches by 3.5 inches in actual size. The nominal length can also refer to the specified length of a board, often measured in feet or inches.
Nominal size is the size of the largest aggregate in a grading.
Mean
A nominal interest rate is an interest rate that does not factor in the rate on inflation. Nominal interest rate could also refer to an interest rate that does not adjust for the full effect of compounding.

That means Nominal Diameter is 300 mm
NB (nominal bore) is the European designation equivalent to NPS is DN (diamètre nominal/nominal diameter/Durchmesser nach Norm), in which sizes are measured in millimeters. NB (nominal bore) is also frequently used interchangeably with NPS.You can refer more details herehttp://www.piping-engineering.com/nominal-pipe-size-nps-nominal-bore-nb-outside-diameter-od.html
DN": Diametre nominel - Nominal diameter of the valve, and "50" is the size of the valve in [mm]. Alternative is NPS (Nominal pipe size in inches).
What does length mean in math
NB stands for "Nominal Bore" and refers to the nominal size of the valve in a piping system, typically measured in inches. It represents the internal diameter of the valve or pipe. It is an important parameter used to select the right valve for a specific application.
NB stands for Nominal Bore.
