Names have been given to each of those divisions of the principal unit; but these names always indicate the value of the fraction and the unit from which it is derived. To the name of the unit have been prefixed, deci, for tenth, centi, for hundredth, and mini, for thousandth. They are thus expressed: a d^cim Otre, a ddcllitre, a d Ocigramme, a ddclst Ore, a ddciare, a centimetre, a centilitre, a centigramme, etc. The facility with which the divisions of the unit are reduced to the same expression is very apparent. As it may sometimes be necessary to express large quantities of units, collections have been made of them in tens, hundreds, thousands, tens of thousands, etc., to which prefixes derived from the Greek have been given namely, deca, for tens; hecto, for hundreds; kilo, for thousands; and myria, for tens of thousands; they are thus expressed: a dicamitre, a dicalitre, etc.; a hecto* metre, a hectogramme, etc.; a kilomitre, a kilogramme, etc. The above act of congress gives the equivalents thus: The Mitre is 89.37 in.
