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).
1 cm – 0.39 inches; 1 cm – edge of a square of area 1 cm 2; 1 cm – edge of a cube of volume 1 mL; 1 cm – length of a coffee bean; 1 cm – approximate width of average fingernail; 1.2 cm – length of a bee; 1.2 cm – diameter of a die; 1.5 cm – length of a very large mosquito; 1.6 cm – length of a Jaragua Sphaero, a very small reptile
Shaku (Japanese: 尺) or Japanese foot [1] [2] is a Japanese unit of length derived (but varying) from the Chinese chi, originally based upon the distance measured by a human hand from the tip of the thumb to the tip of the forefinger [3] [a] (compare span). Traditionally, the length varied by location or use, but it is now standardized as 10/ ...
While its predecessors use Wabco AA2 with factory note tuned to D, G (play perfect 4th mid C), the CC206 locomotives use Nathan 3rd gen P2 (Bell No. 1&4) with factory note tuned to D, A (play perfect 5th mid C), (Unlike the other P2 using Bell No. 1&2 play minor 3rd). One unit of CC206 locomotive could haul up to 16 passenger cars or 30 freight ...
As a measure of length, a pada amounts to 12 or 15 fingers' breadth, or 1/2 or 1/3 or 3/7 of a Prakrama. In Sanskrit grammar, a pada is any inflected word (noun or verb). In Buddhism, pāda is the term for a Buddha footprint. Gautama Buddha's footprints symbolized his presence, and his image and iconography developed several centuries after he ...
The United States retained the 1 / 39.37 -metre definition for surveying, producing a 2 millionth part difference between standard and US survey inches. [47] This is approximately 1 / 8 inch per mile; 12.7 kilometres is exactly 500,000 standard inches and exactly 499,999 survey inches.
[1] [2] By the barometric formula, 1 bar is roughly the atmospheric pressure on Earth at an altitude of 111 metres at 15 °C. The bar and the millibar were introduced by the Norwegian meteorologist Vilhelm Bjerknes , who was a founder of the modern practice of weather forecasting , with the bar defined as one mega dyne per square centimeter .
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.
