30 cm = 3 dm – typical school-use ruler length (= 300 mm) 30.48 cm = 3.048 dm – 1 foot (measure) 60 cm = 6 dm – standard depth (front to back) of a domestic kitchen worktop in Europe (= 600 mm) 90 cm = 9 dm – average length of a rapier, a fencing sword [30] 91.44 cm = 9.144 dm – one yard (measure)
A scale ruler is a scaled, three-edged ruler which has six different scales marked to its sides. A typical combination for building details is 1:20, 1:50, 1:100, 1:25, 1:75 and 1:125. There are separate rulers for zoning work as well as for inch units. Today scale rulers are made of plastic, formerly they were made of hardwood. A pocket-sized ...

1/52! chance of a specific shuffle Mathematics: The chances of shuffling a standard 52-card deck in any specific order is around 1.24 × 10 −68 (or exactly 1 ⁄ 52!) [4] Computing: The number 1.4 × 10 −45 is approximately equal to the smallest positive non-zero value that can be represented by a single-precision IEEE floating-point value.
2. 6:1 = 8:3 = 24:9 Full-frame output from Super 16 mm negative when an anamorphic lens system has been used. Effectively, an image that is of the ratio 24:9 is squashed onto the native 15:9 aspect ratio of a Super 16 mm negative.
Illustration of the relationship between optical power in dioptres and focal length in metres. A dioptre (British spelling) or diopter (American spelling), symbol dpt or D, is a unit of measurement with dimension of reciprocal length, equivalent to one reciprocal metre, 1 dpt = 1 m −1.
A fathom is a unit of length in the imperial and the U.S. customary systems equal to 6 feet (1.8288 m), used especially for measuring the depth of water. [1] The fathom is neither an international standard (SI) unit, nor an internationally accepted non-SI unit.
The Sigma 24mm f/1.8 EX DG is wide-angle lens which features a fast f/1.8 maximum aperture for use in low-light situations, and macro focusing capability to a reproduction ratio of 1:2.7.
