  2. French catheter scale - Wikipedia

    en.wikipedia.org/wiki/French_catheter_scale

    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. This metrication problem is further complicated in medical contexts where metric and imperial units are used interchangeably

  3. General Motors LS-based small-block engine - Wikipedia

    en.wikipedia.org/wiki/General_Motors_LS-based...

    Dubbed EcoTec3, the 4.3 L (260 cu in) is a Generation V small block V6 truck engine. It gets its displacement from bore and stroke of 99.6 mm × 92 mm (3.921 in × 3.622 in) with a compression ratio of 11.0 to 1. Firing order is 1-6-5-4-3-2. [85] This engine replaces the unrelated 4.3L V6 whose lineage dates back to 1978.

  4. 4 bore - Wikipedia

    en.wikipedia.org/wiki/4_bore

    This would imply a bore diameter of 1.052-inch (26.7 mm), however in practice the bore diameter varied greatly as, in muzzle loader days, shotgun gauges were custom made and often differed from the actual bore measurements. Commonly, 4 bores were closer to 0.935–0.955 in (23.7–24.3 mm) calibre, which is closer to 5 gauge.

    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. Very close to wargaming 20 mm figure scale (20 mm is actually 1:80.5). [10] 1:76.2: 4 mm: Model ...

  7. Pentium 4 - Wikipedia

    en.wikipedia.org/wiki/Pentium_4

    The Prescott Pentium 4 contains 125 million transistors and has a die area of 112 mm 2. [33] [34] It was fabricated in a 90 nm process with seven levels of copper interconnect. [34] The process has features such as strained silicon transistors and low-κ carbon-doped silicon oxide (CDO) dielectric, which is also known as organosilicate glass ...

    en.wikipedia.org/wiki/Coaxial_power_connector

    There are a number of sizes listed below that appear to be quite similar, and while the tolerances of these connectors are typically indicated as ±0.05 or ±0.03 mm by the manufacturers, there is still ambiguity as to whether two sizes differing by only 0.05 mm (or where the specification is only given to the nearest 0.10 mm) warrants listing ...

    24 mm × 5 mm × 32 mm. Toshiba announced this form factor in January 2004 for use in mobile phones and similar applications, including SD/MMC slot compatible HDDs optimized for video storage on 4G handsets. Toshiba manufactured a 4 GB (MK4001MTD) and an 8 GB (MK8003MTD) version and holds the Guinness World Record for the smallest HDD.
