Ancient Roman Units Of Measurement
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 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 Villalpandus, a number of brass measuring-rods found in the ruins of Rome, the paving-stones of the 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 Guildhall in London William Smith (1851) gives a value ...

Perch (unit)
The rod, perch, or pole (sometimes also lug) is a surveying, surveyor's tool and unit of length of various historical definitions. In Imperial units, British imperial and United States customary units, US customary units, it is defined as Foot (unit), feet, equal to exactly of a mile, or yards (a quarter of a surveyor's chain), and is exactly 5.0292 meters. The rod is useful as a unit of length because integer multiples of it can form one acre of square measure (area). The 'perfect acre' is a rectangular area of 43,560 square feet, bounded by sides 660 feet (a furlong) long and 66 feet (a Chain (unit), chain) wide (220 yards by 22 yards) or, equivalently, 40 rods by 4 rods. An acre is therefore 160 square rods or 10 square chains. The name ''perch'' derives from the Ancient Roman units of measurement, Ancient Roman unit, the ''pertica (unit), pertica''. The measure also has a relationship with the military pike (weapon), pike of about the same size. Both measures date from ...

Pertica (unit)
The pertica (from , measuring rod) was a pre- metric unit of either length or area, with the values varying by location. For a similar unit in Northern Europe, see perch. Ancient Rome In the Ancient Rome, pertica, also called decempeda, was a unit of length, usually equal to 10 Roman feet (''pedes''), or approximately 2.96 meters. The variants of pertica contained 12 and 15 pedes. Isidore of Seville (per Codex Gudianus) states that sometimes a pertica of 10, 12, 15, or 17 pedes was used by agrimensores (Roman land surveyors) to accommodate the richness of the soil and approximately even the yield per unit area. Kidson highlights the near-perfect match between the pertica of 17 pedes and the English version of the perch. The same names, pertica and decempeda, were used for the surveyor's tool, a rod of the corresponding length with subdivision into smaller units, similar to the Ancient Greek ''kalamos''.

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 ...

Palmus Maior
The hand is a non- SI unit of measurement of length standardized to . It is used to measure the height of horses in many English-speaking countries, including Australia, Canada, Ireland, the United Kingdom, and the United States. It was originally based on the breadth of a human hand. The adoption of the international inch in 1959 allowed for a standardized imperial form and a metric conversion. It may be abbreviated to "h" or "hh". Although measurements between whole hands are usually expressed in what appears to be decimal format, the subdivision of the hand is not decimal but is in base 4, so subdivisions after the radix point are in quarters of a hand, which are inches. Thus, 62 inches is fifteen and a half hands, or 15.2 hh (normally said as "fifteen-two", or occasionally in full as "fifteen hands two inches"). Terminology "Hands" may be abbreviated to "h", or "hh". The "hh" form is sometimes interpreted as standing for "hands high". When spoken aloud, hands are ...
