The Egyptian equivalent of the foot—a measure of four palms or 16 digits—was known as the djeser and has been reconstructed as about 30 cm (11.8 in). The Greek foot ( πούς , pous ) had a length of 1 / 600 of a stadion , [ 12 ] one stadion being about 181.2 m (594 ft); [ 13 ] therefore a foot was, at the time, about 302 mm (11.9 in).
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 ...
The thousand legs house generally has dimensions of 8 x 6 meters. The height of the platform measured from the ground is around 1 - 1.5 meters. The peak roof height ranges from 4.5 to 5 meters. The pillars are made of wood with a diameter of 10 cm. The foundation pillars of the house are very close together, spaced about 30 cm apart.
In the US lighting industry, foot-candles are a common unit of measurement used by architects to calculate adequate lighting levels. Foot-candles are also commonly used in the museum and gallery fields in the US, where lighting levels must be carefully controlled to conserve light-sensitive objects such as prints, photographs, and paintings, the colors of which fade when exposed to bright ...
1. 3:1 = 4:3 = 12:9 35 mm original silent film ratio, today commonly known in TV and video as 1.33:1. Also standard ratio for MPEG-2 video compression. This format is still used in many personal video cameras today and has influenced the selection or design of other aspect ratios. It is the standard Super 35 mm ratio. 1.37:1 ~ 48:35
Different lengths as in respect to the electromagnetic spectrum, measured by the metre and its derived scales.The microwave is in-between 1 meter to 1 millimeter.. A centimetre or centimeter (US/Philippine spelling), with SI symbol cm, is a unit of length in the International System of Units (SI) equal to one hundredth of a metre, centi being the SI prefix for a factor of 1 / 100 .

Most digital point-and-shoot cameras have an aspect ratio of 1.33 (4:3), the same as analog television or early movies. However, a 35 mm picture's aspect ratio is 1.5 (3:2). Several [quantify] digital cameras take photos in either ratio. Nearly all digital SLRs take pictures in a 3:2 ratio, as most can use lenses designed for 35 mm film.
Spatial frequency is a reciprocal length, which can thus be used as a measure of energy, usually of a particle. For example, the reciprocal centimetre, cm −1, is an energy unit equal to the energy of a photon with a wavelength of 1 cm. That energy amounts to approximately 1.24 × 10 −4 eV or 1.986 × 10 −23 J.
