T scale, using 3 mm gauge track to represent 3 ft 6 in (1,067 mm) gauge railways. Hasegawa also produces plastic ship models in this scale. 1:432: 0.706 mm The scale used during World War II by the U.S. Navy for aircraft recognition. 1:426: 0.028: 0.715 mm Scale used by Revell for USS Arizona, Pennsylvania, Norton Sound, and Pine Island ships.
The 37.5 mm length is not derived by a certain scale ratio. While HO scale is a 1:87 scale (3.5 mm to 1 foot), resulting in a 16.5 mm (0.65 in) gauge from real life prototype 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge standard gauge. Conversely, modeling standard gauge in Lego trains would yield a scaling of (37.5:1435 =) 1:38.3.
1.5 mm – average length of a flea [27] 2.54 mm – distance between pins on old dual in-line package (DIP) electronic components; 5 mm – length of an average red ant; 5 mm – diameter of an average grain of rice; 5.56×45mm NATO – standard ammunition size; 6 mm – approximate width of a pencil

The first group of metric units are those that are at present defined as units within the International System of Units (SI). In its most restrictive interpretation, this is what may be meant when the term metric unit is used. The unit one (1) is the unit of a quantity of dimension one. It is the neutral element of any system of units. [2]
The O-27 name comes from the size of the track's curves. A circle made of eight pieces of standard 45-degree curved O gauge track will have a 31 inches (787 mm) diameter. A circle made of 8 pieces of 45-degree curved O-27 track is smaller, with a 27 inches (686 mm) diameter.
The French scale measures the outer diameter of the catheter, not the size of the internal drainage channel (inner diameter). For instance, a two-way catheter of 20 Fr and a three-way catheter of 20 Fr have the same outer diameter, but the three-way catheter has an additional channel for irrigation, reducing the size of its drainage channel.
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.
