<P> Deci - ( symbol d ) is a decimal unit prefix in the metric system denoting a factor of one tenth . Proposed in 1793 and adopted in 1795 , the prefix comes from the Latin decimus , meaning `` tenth '' . Since 1960 , the prefix is part of the International System of Units ( SI ) . Its most frequent use , however , is in a non-SI unit , the decibel , used to measure sound intensity ( relative to a reference ) and many other ratios . </P>
