	Units: Customary Units
		Because of their many eccentricities, English customary units clearly are more cumbersome to use than metric units in trade and in science.
		Thus the gallon, the basic English unit of volume, was originally the volume of eight pounds of wheat.
		Most area units were eventually defined to be the area of a square having sides equal to some simple multiple of a distance unit, like the square yard.

	Units of Measurement
		Caught in a slow-moving transition from customary to metric units, we employ a fascinating and sometimes frustrating mixture of units in talking about the same things.
		Furthermore, our English customary units do not form a consistent system.
		Meanwhile, only a few Americans know that the legal definitions of the English customary units are actually based on metric units.

	SI - Wikipedia, the free encyclopedia
		The presence of these adjustments has been one reason advocates of the U.S. customary units had used against metrication; these customary units, however, are nowadays defined in terms of SI units, thus any difference in the definition of the SI units results in a difference of the definition of the customary units.

		The six base units recommended were the metre, kilogram, second, ampere, Kelvin degree (later renamed the kelvin), and the candela.

	SI - Wikipedia, the free encyclopedia
		Since most non-SI units, such as the U.S. customary units, are nowadays defined in terms of SI units, any change in the definition of the SI units results in a change of the definition of the older units as well.

		The swift worldwide adoption of the metric system as a tool of economy and everyday commerce was based mainly on the lack of customary systems in many countries to adequately describe some concepts, or as a result of an attempt to standardize the many regional variations in the customary system.

	The Unified Code for Units of Measure
		In short, each unit is defined relative to a system of base units by a numeric factor and a vector of exponents by which the base units contribute to the unit to be defined.
		Fortunately these units are rather rare in everyday use in trade and medicine, however, we must urge everyone to regenerate their tables, dictionaries, and knowledge bases, and check their data immediately based on this corrected release of The Unified Code for Units of Measure.
		The units directly affected by this error were: unified atomic mass unit (u), parsec (pc), Planck's constant [h], Boltzman's constant [k], electric permittivity ([eps_0]), elementary charge ([e]), electron mass ([m_e]), proton mass ([m_p]), Newton's constant of gravitation ([G]), Maxwell (Mx), Gauss (G), phot (ph), Curie (Ci), Roentgen (R), and U.S. and international mil ([mil_i], [mil_us]).

	Units of Measurement
		Units belonging to the U.S. Customary measurement system will crop up periodically since the primary sources of information about nuclear weapons in general are from the United States and I have not tried to convert all measurements from U.S. sources to metric yet.
		Normally this is used as a unit of mass or weight (a distinction I am going to ignore) in either the Metric, British Imperial, or U.S. Customary measurement systems (the last two both having two types of tons, short and long).
		These units are outside the SI system, but are recognized by the SI standards as anciliary metric units to be discouraged and eventually phased out.

		As noted above, in the customary British system the units of dry measure are the same as those of liquid measure.
		In the United States these two are not the same, the gallon and its subdivisions are used in the measurement of liquids; the bushel, with its subdivisions, is used in the measurement of certain dry commodities.

	Units of measurement - Wikipedia, the free encyclopedia
		US customary units are the main system of measurement in the United States however some steps towards metrication have been made.
		One example of the importance of agreed units is the failure of the NASA Mars Climate Orbiter, which crashed on the planet Mars in September 1999 instead of entering orbit, due to miscommunications about the value of forces: different computer programs used different units of measurement (newton versus pound force).
		Different systems of units are based on different choices of a set of fundamental units.

		In the United States and in a few Caribbean countries, the U.S. customary units, which are similar to Imperial units based upon older English units and in part share definitions, are still in common use.
		The use of SI units is increasingly mandated by law for the retail sale of food and other commodities, but most British people still use Imperial units in colloquial discussion of distance (miles and yards), speed (miles per hour), weight (stones and pounds), liquid (pints and gallons) and height (feet and inches).
		Traditional units persist in ordinary conversation and may be experiencing a resurgence due to the reduction in trade barriers with the United States.

		Squares and cubes of customary but not of metric units are sometimes expressed by the use of abbreviations rather than symbols.
		TABLES OF METRIC UNITS OF In the metric system of measurement, designations of multiples and sub-divisions of any unit may be arrived at by combining with the name of the unit the prefixes deka, hecto, and kilo meaning, respectively, 10, 100, and 1000, and deci, centi, and milli, meaning, respectively, one-tenth, one-hundredth, and one-thousandth.

	Units: L
		Compared to the customary volume units, the liter is a little more than a U. liquid quart (1.056 688 qt or 33.814 fluid ounces) but a little less than a U. dry quart (0.908 08 qt) or a British imperial quart (0.879 89 qt or 35.195 fluid ounces).
		The unit was called the line because magnetic fields were traditionally represented by lines depicting the direction of the field; the idea was to quantify the strength of these lines.
		The intensity of the light source is measured in candelas ; the total light flux in transit is measured in lumens (1 lumen = 1 candela·steradian); and the amount of light received per unit of surface area is measured in lux (1 lux = 1 lumen/square meter).

	Units: The Metric System
		Prior to the introduction of the metric system, it was common for units of length, land area, and weight to vary, not just from one country to another but from one region to another within the same country.
		The metric system has been the customary measurement system in France for almost two centuries, in the rest of continental Europe for at least one century, and in the rest of the world for a least a generation or two.
		These prefixes denote powers of ten, so that metric units are always divided into tens, hundreds, thousands, etc. The original prefixes included milli- for 1/1,000, centi- for 1/100, deci- for 1/10, deka- for 10, hecto- for 100, and kilo- for 1,000.
