Wikipedia Meaning and Definition on 'Decameter'
A decametre or dekametre (American spelling: dekameter, earlier decameter; symbol dam) is a very rarely used unit of length in the metric system, equal to ten metres, the SI base unit of length. It can be written in scientific notation as 1 E+1 m (exponential notation), meaning 10 × 1 m.
This measure is included mostly for completeness. One practical use of the decameter is for altitude of geopotential heights (circumscribing equal pressure) in meteorology. Interestingly, meteorologists also use another seldom encountered SI prefix: hecto- in hectopascal (hPa). The volumetric form (see below) cubic decametre is convenient for describing large volumes of water such as in rivers and lakes.[See more about Decameter at Dictionary 3.0 Encyclopedia]
