2 mm scale, often 2 mm finescale is a specification used for railway modelling, [1] largely for modelling British railway prototypes. [citation needed] It uses a scale of 2 mm on the model to 1 foot on the prototype, which scales out to 1:152. [1] The track gauge used to represent prototype standard gauge (4 feet 8 + 1 ⁄ 2 inches) is 9.42 mm ...
A size chart illustrating the ANSI sizes. In 1992, the American National Standards Institute adopted ANSI/ASME Y14.1 Decimal Inch Drawing Sheet Size and Format, [1] which defined a regular series of paper sizes based upon the de facto standard 8 + 1 ⁄ 2 in × 11 in "letter" size to which it assigned the designation "ANSI A".
The dominant European size for die-cast ship models, most comprehensive range. 1:1200: 0.01 0.254 mm: Ship models: A British and American size for ship and harbour models. Airfix used to produce in this scale. 1:1000: 0.305 mm This is a scale used in Germany for pre-finished airliner models. Herpa and Hogan Wings produces several models in this ...
Problematically, some manufacturers are developing metric 0201 components with dimensions of 0.25 mm × 0.125 mm (0.0098 in × 0.0049 in), [31] but the imperial 01005 name is already being used for the 0.4 mm × 0.2 mm (0.0157 in × 0.0079 in) package. These increasingly small sizes, especially 0201 and 01005, can sometimes be a challenge from ...
(E.g. 1 mm diameter wire is ~18 AWG, 2 mm diameter wire is ~12 AWG, and 4 mm diameter wire is ~6 AWG). This quadruples the cross-sectional area and conductance. A decrease of ten gauge numbers (E.g. from 12 AWG to 2 AWG) multiplies the area and weight by approximately 10, and reduces the electrical resistance (and increases the conductance ) by ...
Size steps between gauges range from 0.001 inches (0.025 mm) between high gauge numbers to 0.046 inches (1.2 mm) between the two lowest gauge numbers and do not correspond to a particular mathematical pattern, although for the most part the steps get smaller with increasing gauge number. [3]
In the United States, the alcohol industry switched to metric bottle sizes on October 1, 1976, abandoning the existing 38 sizes of bottles and instead adopting the following 6 sizes: [2] 50 mL (miniature) 200 mL (replaced the half-pint) (≈237 mL is a U.S. half-pint) 500 mL (replaced the pint) (≈473 mL is a U.S. pint)
For example, a 2 mm taper pin reamer has a 1.9 mm small end (2 mm nominal size) and a 2.86 mm large end. ... The size or gauge is defined by diameter at each end, and ...
