  2. Orders of magnitude (length) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(length)

    The millimetre (SI symbol: mm) is a unit of length in the metric system equal to 10 −3 metres (⁠ 1 / 1 000 ⁠ m = 0.001 m). To help compare different orders of magnitude, this section lists lengths between 10 −3 m and 10 −2 m (1 mm and 1 cm). 1.0 mm – 1/1,000 of a meter; 1.0 mm – 0.03937 inches or 5/127 (exactly)

  3. French catheter scale - Wikipedia

    Thus, the outer diameter of a catheter in millimeters can be calculated by dividing the French size by 3. [2] For example, a catheter with a French size of 9 would have an outer diameter of approximately 3 mm. While the French scale aligns closely with the metric system, it introduces redundancy and the potential for rounding errors.

    3.503 mm: Model railways (HO/h0) Civilian and military vehicles. Often used to describe HO scale. Original nominal 25 mm figure scale; though a 6-foot human in 1:87 is closer to 21 mm. 1:82: 3.717 mm An intermediate scale (HO/OO) intended to apply to both HO and OO scale train sets. Also used for some military models 1:80: 3.810 mm HOj scale.

    Different lengths as in respect to the electromagnetic spectrum, measured by the metre and its derived scales.The microwave is between 1 meter to 1 millimeter.. The millimetre (international spelling; SI unit symbol mm) or millimeter (American spelling) is a unit of length in the International System of Units (SI), equal to one thousandth of a metre, which is the SI base unit of length.

  6. Nominal Pipe Size - Wikipedia

    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 ...

  7. Engineering tolerance - Wikipedia

    en.wikipedia.org/wiki/Engineering_tolerance

    The actual amount bigger/smaller depends on the base dimension. For a shaft of the same size, h6 would mean 10+0−0.009, which means the shaft may be as small as 0.009 mm smaller than the base dimension and 0 mm larger. This method of standard tolerances is also known as Limits and Fits and can be found in ISO 286-1:2010 (Link to ISO catalog).

    For example, "agate" and "ruby" used to be a single size "agate ruby" of about 5 points; [2] metal type known as "agate" later ranged from 5 to 5.8 points. The sizes were gradually standardized as described above. [ 3 ]
