In dynastic China, the kè was a unit that represented 1 ⁄ 100 of a day (it has since been redefined to 1 ⁄ 96 of a day, or 15 minutes). In France, a decimal time system in place from 1793 to 1805 divided the day into 10 hours, each divided into 100 minutes, in turn each divided into 100 seconds; the French Republican Calendar further ...
1:72 scale is a scale used for scale models, most commonly model aircraft, where one inch on the model equals six feet (which is seventy-two inches) in real life. The scale is popular for aircraft because sizes ranging from small fighters to large bombers are all reasonably manageable and displayable.
Baden, in 1810, for example, redefined the Ruthe (rods) as being 3.0 m exactly and defined the subunits of the Ruthe as 1 Ruthe = 10 Fuß (feet) = 100 Zoll (inches) = 1,000 Linie (lines) = 10,000 Punkt (points) (for simplicity at the expense of grammar, these are the singular forms of each name) while the Pfund was defined as 500 g, divided ...
The division of the circle into 360 degrees and the day into hours, minutes, and seconds can be traced to the Babylonians who had a sexagesimal system of numbers. The 360 degrees may have been related to a year of 360 days. Many other systems of measurement divided the day differently—counting hours, decimal time, etc.
The length of the metre was established, in relation to the toise of the Academy also called toise of Peru, at 3 feet 11.44 lines, taken at 13 degrees of the temperature scale of René-Antoine Ferchault de Réaumur in use at the time. It was therefore metal bars of this length that were distributed in the country in 1795/1796.
A popular collectible model is the Keuffel & Esser Deci-Lon, a premium scientific and engineering slide rule available both in a ten-inch (25 cm) "regular" (Deci-Lon 10) and a five-inch "pocket" (Deci-Lon 5) variant. Another prized American model is the eight-inch (20 cm) Scientific Instruments circular rule.
A fleeting hint of an ancient decimal or metric system may be found in the Mohenjo-Daro ruler, which uses a base length of 1.32 inches (33.5 mm) and is very precisely divided with decimal markings. Bricks from that period are consistent with this unit, but this usage appears not to have survived, as later systems in India are non-metric ...
Nashville's elevation ranges from its lowest point, 385 feet (117 m) above sea level at the Cumberland River, [98] to its highest point, 1,163 feet (354 m) above sea level in the Radnor Lake State Natural Area. [99] [100] Nashville also sits at the start of the Highland Rim, a geophysical region of very hilly land. Because of this, Nashville is ...
