    The metric ton is the name used for the tonne (1000 kg, 2 204.622 62 lb), which is 1.58% less than the long ton and is 10.23% more than the short ton. The US customary system also includes the kip , equivalent to 1,000 pounds of force, which is also occasionally used as a unit of weight of 1,000 pounds (usually in engineering contexts).

    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 mm1/1,000 of a meter; 1.0 mm – 0.03937 inches or 5/127 (exactly) 1.0 mm – side of a square of area 1 mm²; 1.0 mm – diameter of a pinhead; 1.5 mm – average length of a flea [27]

  5. Caliber - Wikipedia

    en.wikipedia.org/wiki/Caliber

    While modern firearms are generally referred to by the name of the cartridge the gun is chambered for, they are still categorized together based on bore diameter. [citation needed] For example, a firearm might be described as a "30 caliber rifle", which could accommodate any of a wide range of cartridges using a roughly 0.30 inches (7.6 mm) projectile; or as a "22 rimfire", referring to any ...

    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 ...

    Thickness of aluminum foil is measured in mils (1 ⁄ 1000 inch, or 0.0254 mm) in the United States. Cross-sectional area of electrical wire is measured in circular mils in the U.S. and Canada, one circular mil (cmil) being equal to 5.067 × 10 −4 mm 2 (or 7.854 × 10 −7 in 2 ).

  8. French catheter scale - Wikipedia

    en.wikipedia.org/wiki/French_catheter_scale

    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.
