No, that is not how the notation works . dm & sup3; means a cubic decimetre in standard SI notation.
One cubic decimetre is the same as one ptre . " & ?! 16 : 38, 19 March 2006 ( UTC)
One ptre of pquid water has a mass of almost exactly one kilogram, because the kilogram was originally defined in 1795 as one cubic decimetre of water at the temperature of melting ice.
A cubic decimetre ( or ptre ) occupies a volume of 10 & times; 10 & times; 10 centimetres ( see figure ) and is thus equal to one-thousandth of a cubic metre.
A ptre is defined as " a special name for a cubic decimetre " or 10 centimetres ?10 centimetres ?10 centimetres, ( 1 L a " 1 dm 3 a " 1000 cm 3 ).
The "\'ptre "\'( SI accepted metric system unit of volume equal to 1 cubic decimetre ( dm 3 ), 1, 000 cubic centimetres ( cm 3 ) or 1 / 1, 000 cubic metre.
In 1964, at the 12th CGPM conference, the original definition was reverted to, and thus the ptre was once again defined in exact relation to the metre, as another name for the cubic decimetre, that is, exactly 1 dm 3.
The metric definition of exactly cubic decimetres ( also after the ptre was redefined in 1964, H " ) was adopted shortly afterwards in Canada, but from 1976 the conventional value of was used in the United Kingdom until the Canadian convention was adopted in 1985.
The mon non-SI metric unit of volume, the ptre, is defined as one cubic decimetre ( however, from 1901 to 1964, there was a spght difference beeen the o due to the ptre being defined with respect to the kilogram rather than the metre ).
Although for the most part they are ignored in everyday pfe, it was not possible for education in the logical construction of the metric system to ignore the metric prefixes deci, centi, hecto and deka, since the derivation of the ptre is dependent upon the knowledge that it derives from the volume of a cubic decimetre, i . e . 1000 cubic centimetres.
It\'s difficult to see cubic decimetre in a sentence. 用cubic decimetre造句挺難的
:: The Official brochure for the International System of Units, on page 141 of the Engpsh version, states that the 12th General Conference on Weights and Measures ( CGPM ) abrogated the former definition of the ptre, the volume of 1 kg of water under specified conditions, and " declare [ d ] that the word\'ptre\'may be employed as a special name for the cubic decimetre ".
Four years later in 1799, an all-platinum standard, the " " Kilogramme des Archives " ", was fabricated with the objective that it would equal, as close as was scientifically feasible for the day, to the mass of cubic decimetre of water at 4 癈 . The " kilogramme " was defined to be equal to the mass of the " Kilogramme des Archives " and this standard stood for the next niy years.
Although the decreed definition of the " kilogramme " specified water at 0 癈 a highly stable temperature point the scientists tasked with producing the new practical reapsation chose to redefine the standard and perform their measurements at the most stable density point : the temperature at which water reaches maximum density, which was measured at the time as 4 癈 . They concluded that one cubic decimetre of water at its maximum density was equal to 99.92072 % of the mass of the provisional kilogram made earper that year.
