Where is the standard metric system keeped?

While it originated in France, the metric system is based on easily observable phenomena in nature (the meter is a certain number of wavelengths of light, the kilogram is the weight of a certain amount of pure water, etc.) so there is no longer any need to keep a "standard meter bar of platinum" or a "standard kilogram at sea level" anywhere.

The SI (metric) unit used to measure mass is the gram.\n\nThe Imperial (English) unit used to measure mass is pounds and ounces.

America's conversion to metric is the law:http://ts.nist.gov/WeightsAndMeasures/Metric/pub814.cfm#act\n\nIt's just voluntary.\n\nHowever, all the units you listed are metric.  The prefixes you're confused about are metric prefixes.

Depends what country you buy it in, more than anything else.  The two most common are English and metric.  English starts with fluid ounces as smallest unit, metric starts with milliters as the smallest.\n\nWhat else might your question mean?

mm cm dm m km\nmillimetre, centimetre, decimetre, metre, kilometre,\n\nwoops - thats the least to greatest - turn it around

England....they predate the metric system, for example a "foot" is roughly the length of an adult male's foot.\nNot sure why we don't use the metric system.  There was a big push to switch when I was in elementary school, but it never happened.

MKS is a set of metric units based on metres, kilograms and seconds (hence the initials). The alternative set of units, no longer commonly used, are cgs which are based on centimetres, grams and seconds.\n\nThe units of magnetic flux density, henries, are defined in MKS units.

there are seven base si units\n\nmetre (m)\nsecond (s)\nkilogram (kg)\nampere  (A)\ncandela\ncoulomb (C)\ncant remember the last one\n\n#edit# yup its kelvin,thanks

D) 5.9cm \n\n10 mm = 1 cm\n\nThis is why the metric system is so much easier than the english system.\n\njust think about all of the wasted brain power trying to figure inches feet miles etc...

Yes. It's like sweet, sweet, mathematical unification of the world! Many parts of the world has already been using the Metric System, except for various countries like the US. The rules of the Metrics, is simplier than the Customs. (cm)Each unit of the measurement is in 10s, as inch, make it hard to make specific measures because each mark on the ruler is 0.0625! Adopting the Metric System!

FPS you mean!  In SI, it is a mertric system which has been standaridized- basic units are Kg for weight, Newtons for force, Metre for length, where as in FPS System of units based on the foot, pound, and second as units of length, mass, and time, respectively. It has now been replaced for scientific work by the SI system.\n\nUnited states uses FPS system and much of Europe, India use MKS (precursor to SI) system (System of units in which the base units metre, kilogram, and second replace the centimetre, gram, and second)

That's like asking why the US uses inches, feet, etc., instead of the metric system (which the rest of the world uses).  Basically, it's just because we're the US.  No reason.  But it's too much of a hassle to change, apparently, on both counts.

There are several elements:\n- For historical reasons, the USA developed its own system of measurement. This is in fact NOT the imperial system of measurement, although it is based on the imperial system. It is correctly known is te USA system of measurement. The following reference discusses this in more detail.\n- The reasons for changing to metric are well known. However, there are huge costs to doing so. The population has to be reeducated which takes years and during this transistion period there are a lot of difficulties. Factories have to be retooled, machines replaced, and so on. The USA watched Canada switch over and many people felt the costs outweighed the benefits. I speak as a Canadian and as pro-metric, but I recognise the disruption to industry and to the life of older people who struggled with the change.\n- The USA also benefits from a huge internal market. Whereas most countries are largely dependent on foreign trade, the size of the USA market means that they are much less dependent on foreign trade so there is less pressure on them to change to metric to match up with their trading partners. This is less true of smaller countries.\n- There is also people's general resistance to change. The American population as a whole neither wants to nor sees a need to change to metric.\n- The political element is also important. Any senior politician who was strongly pro-metric (and looked like he could force the metric system through) would find this a major liability for his electoral chances.\n- There are also emotional connections to historical items\n\nThe list goes on. It is a complex issue and unlikely to be resolved soon. However, my personal belief is that one day the USA will follow the rest of the world and go metric.

Metric. Thy still use the same ones.

The seven base units of the SI system are:\n\nlength (meter, m)\nmass (kilogram, kg)\ntime (second, s)\nelectric current (ampere, A)\ntemperature (Kelvin, K)\namount of substance (mole, mol)\nluminous intensity (candela, cd)
