Convert from hectometer to military pace [double time]

Unit Definition (hectometer)
A hectometre (American spelling: hectometer, symbol: hm) is a measurement of distance equal to 100 metres. This measure is rarely used and is included mostly for completeness, since usage of the SI prefix hecto is no longer recommended.

Unit Definition (military pace [double time])
The length of a single step in marching (taken to be 30 inches for quick time or 36 inches for double time).
