Pace (unit)
A pace is a unit of length consisting either of one normal walking step (approximately ), or of a double step, returning to the same foot (approximately ). The normal pace length decreases with age and some health conditions. The word "pace" is also used for units inverse to speed, used mainly for walking and running, commonly ''minutes per kilometer''. The word "pace" is also used to translate similar formal units in other systems of measurement. Pacing is also used as an informal measure in surveying, with the "pace" equal to two of the surveyor's steps reckoned through comparison with a standard rod or chain. Standardized units Like other traditional measurements, the pace started as an informal unit of length, but was later standardized, often with the specific length set according to a typical brisk or military marching stride. In the United States the pace is an uncommon customary unit of length denoting a brisk single step and equal to .''U.S. Army Map Reading ...

Units Of Measurement
A unit of measurement, or unit of measure, is a definite magnitude (mathematics), magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit of measurement. For example, a length is a physical quantity. The metre (symbol m) is a unit of length that represents a definite predetermined length. For instance, when referencing "10 metres" (or 10 m), what is actually meant is 10 times the definite predetermined length called "metre". The definition, agreement, and practical use of units of measurement have played a crucial role in human endeavour from early ages up to the present. A multitude of System of measurement, systems of units used to be very common. Now there is a global standard, the International System of Units (SI), the modern form of the metric system.

Roman Mile
The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a British imperial unit and United States customary unit of length; both are based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. The statute mile was standardised between the Commonwealth of Nations and the United States by an international agreement in 1959, when it was formally redefined with respect to SI units as exactly . With qualifiers, ''mile'' is also used to describe or translate a wide range of units derived from or roughly equivalent to the Roman mile (roughly ), such as the nautical mile (now exactly), the Italian mile (roughly ), and the Chinese mile (now exactly). The Romans divided their mile into 5,000 (), but the greater importance of furlongs in the Elizabethan-era England meant that the statute mile was made equivalent to or in 1593. This form of the mile then spread across the British Empire, some successor st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horse Gait
Horses can use various gaits (patterns of leg movement) during Terrestrial locomotion, locomotion across solid ground, either naturally or as a result of specialized horse training, training by humans.Ensminger, M. E. ''Horses and Horsemanship'' 6th edition USA: Interstate Publishers 1990 pp. 65–66 Classification Gait, Gaits are typically categorized into two groups: the "natural" gaits that most horses will use without special training, and the "Ambling gait, ambling" gaits that are various smooth-riding, four-beat footfall patterns that may appear naturally in some individuals. Special training is often required before a horse will perform an ambling gait in response to a equestrianism, rider's command. Another system of classification that applies to Quadrupedalism, quadrupeds uses three categories: walking and ambling gaits, running or trotting gaits, and leaping gaits.Tristan David Martin Roberts (1995) ''Understanding Balance: The Mechanics of Posture and Locomotion'', ...

Pace Count Beads
Pace count beads, pacer beads or ranger beads are a manual counting tool used to keep track of distance traveled through a pace count. It is used in military land navigation or orienteering. Stringed beads found at stoneage sites in Africa may have been used for pace counting, and modified Japamala have been used to keep pace. A typical example for military use is keeping track of distance traveled during a foot patrol. Description The tool is usually constructed using a set of about 13 beads on a length of cord. The beads are divided into two sections, separated by a knot. Nine beads are used in the lower section, and four (or in some cases more) beads are used in the upper section. There is often a loop in the upper end, making it possible to attach the tool to the user's gear with a simple Larks head hitch. Usage The beads can be used to count paces or a distance calculated from the number of paces. Both methods require the user to know the relationship between the paces ...

Roman Units
The units of measurement of ancient Rome were generally consistent and well documented. Length The basic unit of Roman linear measurement was the ''pes'' (plural: ''pedes'') or Roman foot. Investigation of its relation to the English units#Length, English foot goes back at least to 1647, when John Greaves published his ''Discourse on the Romane foot''. Greaves visited Rome in 1639, and measured, among other things, the foot measure on the tomb of Titus Statilius Aper, that on the statue of Cossutius formerly in the gardens of Angelo Colocci, the congius of Vespasian previously measured by Juan Bautista Villalpando, Villalpandus, a number of brass measuring-rods found in the ruins of Rome, the paving-stones of the Pantheon, Rome, Pantheon and many other ancient Roman buildings, and the distance between the milestones on the Appian Way. He concluded that the Cossutian foot was the "true" Roman foot, and reported these values compared to the iron standard of the English foot in the ...

Bematist
Bematist (), plural bematists or bematistae (), meaning 'step measurer' (from βῆμα ''bema'', meaning 'step, pace'), were specialists in ancient Greece and ancient Egypt who measured distances by pacing. Measurements of Alexander's bematists Bematists accompanied Alexander the Great on his campaign in Asia. Their measurements of the distances traveled by Alexander's army show a high degree of accuracy to the point that it had been suggested that they must have used an odometer, although there is no direct mentioning of such a device: The table below lists distances of the routes as measured by two of Alexander's bematists, Diognetus and Baeton. They were recorded in Pliny's Naturalis Historia (''NH'' 6.61–62). Another similar set of measurements is given by Strabo (11.8.9) following Eratosthenes. Eratosthenes calculated the circumference of the Earth based on work of Egyptian bematists. Notes: 1) 1 mille passus = 2) 1 Attic stadion = 3) The route is not reco ...

Anthropic Units
The term anthropic unit (from Greek ''wikt:άνθρωπος, άνθρωπος'', 'human') is used with different meanings in archaeology, in measurement and in social studies. In archaeology In archaeology, ''anthropic units'' are strata or deposits of material containing a high proportion of man-made detritus.

English Units
English units were the units of measurement used in England up to 1826 (when they were replaced by Imperial units), which evolved as a combination of the Anglo-Saxons, Anglo-Saxon and Ancient Roman units of measurement, Roman systems of units. Various standards have applied to English units at different times, in different places, and for different applications. Use of the term "English units" can be ambiguous, as, in addition to the meaning used in this article, it is sometimes used to refer to the units of the descendant Imperial system as well to those of the descendant system of United States customary units. The two main sets of English units were the Winchester measure, Winchester Units, used from 1495 to 1587, as affirmed by Henry VII of England, King Henry VII, and the Exchequer Standards, in use from 1588 to 1825, as defined by Queen Elizabeth I. In England (and the British Empire), English units were replaced by Imperial units in 1824 (effective as of 1 January 1826) ...

Inch
The inch (symbol: in or prime (symbol), ) is a Units of measurement, unit of length in the imperial units, British Imperial and the United States customary units, United States customary System of measurement, systems of measurement. It is equal to yard or of a foot (unit), foot. Derived from the Uncia (unit), Roman uncia ("twelfth"), the word ''inch'' is also sometimes used to translate similar units in other measurement systems, anthropic units, usually understood as deriving from the width of the human thumb. Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s the inch has been based on the metric system and defined as exactly 25.4Millimetre, mm. Name The English word "inch" () was an early borrowing from Latin ' ("one-twelfth; Roman inch; Roman ounce"). The vowel change from Latin to Old English (which became Modern English ) is known as Germanic umlaut, umlaut. The consonant c ...

Welsh Feet
Welsh units of measurement are those in use in Wales between the Sub-Roman period (prior to which the Britons used Roman units) and the 13th-century Edwardian conquest (after which English units were imposed). Modern Wales no longer employs these units even for customary purposes but instead follows the custom as elsewhere in Britain of using a mixture of metric and Imperial units. Length In the Venedotian Code used in Gwynedd, the units of length were said to have been codified by Dyfnwal Moelmud but retained unchanged by Hywel Dda. The code provided for computing the units variously, as well as deriving them from grains of barley. In measuring milk and its legal worth ('), disputes over the length of the inch used in the container were to be resolved by the width of the judge's thumb. The code notes that in some areas of Wales, the rod used to compute the Welsh acre (') was not reckoned from feet but taken to be "as long as the tallest man in the ref with his hand above h ...
