US Customary Units
United States customary units form a system of measurement units commonly used in the United States and most U.S. territories since being standardized and adopted in 1832. The United States customary system developed from English units that were in use in the British Empire before the U.S. became an independent country. The United Kingdom's system of measures evolved by 1824 to create the imperial system (with imperial units), which was officially adopted in 1826, changing the definitions of some of its units. Consequently, while many U.S. units are essentially similar to their imperial counterparts, there are noticeable differences between the systems. The majority of U.S. customary units were redefined in terms of the meter and kilogram with the Mendenhall Order of 1893 and, in practice, for many years before. T.C. Mendenhall, Superintendent of Standard Weights and MeasuresOrder of April 5, 1893, published as Appendix 6 to the Report for 1893 of the United States Co ...

Executive (government)
The executive branch is the part of government which executes or enforces the law. Function The scope of executive power varies greatly depending on the political context in which it emerges, and it can change over time in a given country. In democratic countries, the executive often exercises broad influence over national politics, though limitations are often applied to the executive. In political systems based on the separation of powers, government authority is distributed between several branches to prevent power from being concentrated in the hands of a single person or group. To achieve this, each branch is subject to checks by the other two; in general, the role of the legislature is to pass laws, which are then enforced by the executive, and interpreted by the judiciary. The executive can also be the source of certain types of law or law-derived rules, such as a decree or executive order. In those that use fusion of powers, typically parliamentary systems, such as th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metrication In The United States
Metrication is the process of introducing the International System of Units, also known as SI Units, SI units or the metric system, to replace a jurisdiction's traditional measuring units. United States customary units, U.S. customary units have been defined in terms of metric units since the 19th century, and the SI has been the "preferred system of weights and measures for United States trade and commerce" since 1975 according to United States law. However, conversion was not mandatory and many industries chose not to convert, and U.S. customary units remain in common use in many industries as well as in governmental use (for example, speed limits are still posted in miles per hour). There is government policy and metric (SI) program to implement and assist with metrication; however, there is major social resistance to further metrication. In the U.S., the SI system is used extensively in fields such as science, medicine, electronics, the military, automobile production and ...

Metric Conversion Act
The Metric Conversion Act of 1975 is an Act of Congress that was signed into law by U.S. President Gerald Ford on December 23, 1975. It declared the metric system "the preferred system of weights and measures for United States trade and commerce", but permitted the use of United States customary units in all activities. As Ford's statement on the signing of the act emphasizes, all conversion was to be "completely voluntary". The Act also established the United States Metric Board with representatives from scientific, technical, and educational institutions, as well as state and local governments to plan, coordinate, and educate the U.S. people for the Metrication of the United States. The Metric Board was abolished in 1982 by President Ronald Reagan, largely on the suggestion of Frank Mankiewicz and Lyn Nofziger. Executive Order 12770, signed by President George H. W.

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 ...
