I actually do, because 'meter' is the name of a unit, which is used to 
measure 'length'.

The length is a physical quantity, which is measured in meters (in the 
SI-unit-system), but the meter is not length (because it is a unit and 
not a quantity).


'Space' needs an additional qualifier, because it can have several 
different uses.

Apparently, you want to address the physical space around you with 'space'.

This space is actually three-dimensional.

If you like to eliminate time-dependency, you end up with Euclidean space.

That space has three dimensions of the type length.
