The French scale measures and is proportional to the outer diameter of a catheter, with 1 French (Fr) defined as 1 ⁄ 3 millimeter, making the relationship: 1 mm = 3 Fr. Thus, the outer diameter of a catheter in millimeters can be calculated by dividing the French size by 3. [ 2 ]
000 or 2 mm: 1:152: 9.42 mm (0.371 in) An early predecessor of small scales like N. Developed before World War II and became somewhat popular in the 1950s. No commercial products available. Today The 2mm Scale Association is the force behind the scale and 2 mm scale has become a finescale alternative to the British N-scale. N: 1:148: 9 mm (0. ...

The solar flux unit is a unit of spectral irradiance equal to 10 −22 W⋅m −2 ⋅Hz −1 (100 yW⋅m −2 ⋅Hz −1). The nox (nx) is a unit of illuminance equal to 1 millilux ( 1 mlx ). The nit (nt) is a unit of luminance equal to one candela per metre squared ( 1 cd⋅m −2 ).
Height measurement using a stadiometer. Human height or stature is the distance from the bottom of the feet to the top of the head in a human body, standing erect.It is measured using a stadiometer, [1] in centimetres when using the metric system or SI system, [2] [3] or feet and inches when using United States customary units or the imperial system.
For example, consider a 700c × 23 mm tire, which has a nominal cross-section of 23 mm. 700c wheels have a rim diameter of 622 mm. Hence the wheel diameter is (2 × 23 mm) + 622 mm = 668 mm which is equal to 26.3 inches (rounded to 1 decimal place). 26 inch mountain bicycle wheels have a rim diameter of 559 mm. This ignores factors that ...
The alternative Super series, denoted SnR, nR Plus or nR+, has an aspect ratio of 3∶2 (or as close as possible) and thus provides a better fit for standard 135 film (35 mm) at sizes of 8 inches or above. 5R is twice the size of a 2R print, 6R twice the size of a 4R print and S8R twice the size of 6R. 4D/6D is a newer size for most consumer ...
Most common size for modern wargaming minis, although some miniatures may be up to 35 mm. 35 mm: ≈6.2 mm: ≈1:52 – 1:48: Heroic scale of 32 mm miniatures. 1:50 scale is a popular size for diecast models from European manufacturers. 1:48 is commonly known as quarter scale or American O scale. 40 mm: ≈7 mm: ≈1:45 – 1:43
