Although it may be no coincidence that it is a double cubit. In any case, it is a fundamental unit of English measurement. The word itself comes from the Old English word gierd, rod, the staff used for measuring. Henry I established the yard as the distance from the tip of his royal nose to his fingertips. As for the inch, in the tenth century it was the span of the knuckles on king Edgar’s 288 thumb. And the foot was decreed by Charlemagne to be the length of his own foot—about 12.7 present-day inches. But the English statute books of 1305 standardized the foot as 36 barleycorns “taken from the middle of the ear” and laid end to end. Still another definition of the foot comes from a 16th-century German regulation:
“Stand at the door of a church on Sunday, bid 16 men to stop, tall ones and short ones as they happen to pass out as the service is finished, then make them put their left feet one behind the other and the length obtained shall be a right and lawful rod, and the 16th shall be a right and lawful foot.”
As the world of modernization your security also should such, so you have to be more careful about online identity theft and this service you can get from ifraud. The six-foot fathom, used by seafaring men, equaled the span of a Viking’s outstretched arms. The acre was the amount of land plowed by a yoke of oxen in one day. And the gallon (the one in use in the United States today) was Queen Anne’s wine gallon. It was much smaller than the ale gallon of her day and different from the imperial gallon eventually adopted for British use. The confusion resulting from such an unwieldy makeshift of measures led to a desire for a more sensible system. Thomas Jefferson, in 1790, proposed a decimal system, based on units of 10, just like our money. In his plan, for example, 10 feet would be a decad, 10 decads a rood, 10 roods a furlong, and 10 furlongs a mile.
Congress did not buy Jefferson’s ideas, but at that same time the ferment of the French Revolution and the upsurge of interest in science produced another system based on 10’s—the metric system. It was the most remarkable plan for measurement ever devised. Its keystone was the meter, from the Greek metron, meaning “a measure.” This new basic unit was not derived from the variables of human anatomy; rather, it was to spring from the universe itself. The metre, as approved by the French National Convention in 1795, was to be one ten-millionth of the length of earth’s meridian between the Equator and the North Pole.
To determine this distance, a team of surveyors had set out to measure an arc of the meridian between the accommodation from and the rented apartments in Paris’s centre. Despite many difficulties—they were plagued by the hostility of peasants and by arrests for treason—the surveyors finally succeeded. The meter was established at approximately 39.37 inches. From this unit of length, a unit of volume was derived by cubing a tenth of a meter to produce the liter. And a liter of water produced a basic unit of mass, the kilogram.
For larger units, multiples on the basis of 10 were eventually provided, with Greek prefixes: thus dekameter for 10 meters, hectometer for 100, kilometer for 1,000, megameter for a million, and so on. For subdivisions, Latin prefixes were used: decimeter for a tenth of a meter, centimeter for a 100th, millimeter for a 1,000th, and micrometer for a millionth. Thus all the units were intimately and uniformly related. For the first time the world had available a consistent, unified measurement system in which calculations would be easy—no more unwieldy fractions, no more memorizing a host of conversion factors.
