The millimetre (SI symbol: mm) is a unit of length in the metric system equal to 10 −3 metres ( 1 / 1 000 m = 0.001 m). 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 mm – 1/1,000 of a meter; 1.0 mm – 0.03937 inches or 5/127 (exactly)
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.
2 mm scale, often 2 mm finescale is a specification used for railway modelling, [1] largely for modelling British railway prototypes. [citation needed] It uses a scale of 2 mm on the model to 1 foot on the prototype, which scales out to 1:152. [1] The track gauge used to represent prototype standard gauge (4 feet 8 + 1 ⁄ 2 inches) is 9.42 mm ...
This is a list of firearm cartridges which have bullets in the 4 millimetres (0.16 in) to 4.99 millimetres (0.196 in) caliber range. All measurements are in mm (in).
Standards organizations define sets of sizes that are conventionally manufactured and stocked. For example, British Standard BS 328 defines 230 sizes from 0.2 mm to 25.0 mm. From 0.2 through 0.98 mm, sizes are defined as follows, where N is an integer from 2 through 9: N · 0.1 mm; N · 0.1 + 0.02 mm; N · 0.1 + 0.05 mm; N · 0.1 + 0.08 mm
This article lists firearm cartridges which have a caliber in the 2.00 to 2.99 millimetres (0.079 to 0.118 in) range. All measurements are in mm (in). 2 mm cartridges
The longest distance achieved on 2 mm in the United Kingdom was 35.6 kilometres (22.1 mi) between stations G8ACE and G8KQW on January 16 2016. [5] In Australia, the 2 mm distance record was 19 kilometres (12 mi) set by stations VK3CV and VK3NH on June 11, 2020. [6]
Scale bar is 0.5 mm. Thrips lay extremely small eggs, about 0.2 mm long. Females of the suborder Terebrantia cut slits in plant tissue with their ovipositor, and insert their eggs, one per slit. Females of the suborder Tubulifera lay their eggs singly or in small groups on the outside surfaces of plants. [74]
