    1:120: 12 mm (0.472 in) Track was introduced by Peco in 2022, closely followed by a range of locomotives, rolling stock and track from Hornby. This has the accurate scale and gauge combination of 2.54 mm : 1 ft on 12 mm track, as has been used by European and American hobbyists, who refer to this as TT. TT3 or 3 mm: 1:102: 12 mm (0.472 in)

    So a 1 / 2 in (12.7 mm) diameter drill will be able to drill a hole 4 + 1 / 2 in (114.3 mm) deep, since it is 9 times the diameter in length. A 1 / 8 in (3.175 mm) diameter drill can drill a hole 1 + 5 / 8 in (41.275 mm) deep, since it is 13 times the diameter in flute length.

    Thus the scale and approximate prototype gauge are represented, with the model gauge used (9 mm for H0e gauge; 6.5 mm for H0f gauge) being implied. [ 2 ] The scales used include the general European modelling range of Z, N, TT, H0, 0 and also the large model engineering gauges of I to X, including 3 + 12 , 5, 7 + 1 ⁄ 4 and 10 + 1 ⁄ 4 ...

    en.wikipedia.org/wiki/Nominal_Pipe_Size

    Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
