  3. Circular mil - Wikipedia

    en.wikipedia.org/wiki/Circular_mil

    A circular mil is a unit of area, equal to the area of a circle with a diameter of one mil (one thousandth of an inch or 0.0254 mm). It corresponds to approximately 5.067 × 10−4 mm2. It is a unit intended for referring to the area of a wire with a circular cross section. As the definition of the unit contains π, it is easy to calculate area ...

  4. French catheter scale - Wikipedia

    en.wikipedia.org/wiki/French_catheter_scale

    The Charrière is measured by the ''outer'' diameter, and is defined as 1 Fr = 1/3 mm, and thus 1 mm = 3 Fr; therefore the diameter of a round catheter in millimetres can be determined by dividing the French size by 3. [2] The French units roughly correspond to the outer circumference of the catheter (see table below).

    ⁠ 20 mm / 50 m ⁠ = 0.4 mrad, or 4 clicks with a ⁠ 1 / 10 ⁠ mrad adjustment scope. ⁠ 50 mm / 1000 m ⁠ = 0.05 mrad, or 1 click with a 0.05 mrad adjustment scope. In firearm optics, where 0.1 mrad per click is the most common mrad based adjustment value, another common rule of thumb is that an adjustment of ⁠ 1 / 10 ⁠ mrad changes ...

  6. Gauge (firearms) - Wikipedia

    en.wikipedia.org/wiki/Gauge_(firearms)

    The gauge (in American English or more commonly referred to as bore in British English) of a firearm is a unit of measurement used to express the inner diameter (bore diameter) of the barrel. Gauge is determined from the weight of a solid sphere of lead that will fit the bore of the firearm and is expressed as the multiplicative inverse of the ...

  7. 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. 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 rimfire firearms ...

    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). Since this is so small, actual wire is commonly measured in ...

  9. Conversion of units - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_units

    Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property ...
