I guess it is a matter of perception. Those of us who have a
background in science know that "deci-" is not rare at all and
certainly is attached to other units: decigram, deciliter, and
decimeter. Likewise with "hect(o)-": hectogram, hectoliter, and
hectometer.
"Bel" is an interesting unit. It is not an absolute quantity like a
liter or a meter. Rather, it is the logarithm to base 10 of the
ratio between two different levels of power, voltage, current or
sound intensity. The decibel is ten times that logarithm.
The formation of the word is interesting because, in all other
uses, "deci-" indicates one-tenth of, while "deca-" is used for ten
times.
