What is meant by a dimensionless metric in OSPFv2?

When several equal-cost routes to a destination exist, traffic
 is distributed equally among them. The cost of a route is
 described by a single dimensionless metric? 

Could someone please explain, what is meant by a single dimensionless metric?  thank you.

Hmm, I just tried Alex's link, and it didn't work for me.

Basically, OSPF uses a single metric for costing a path, and that metric has no implicit connection to the topology.

Cisco OSPF devices often set OSPF costs to reflect link bandwidths (a dimension of the topology), but although often a good scheme, it's not part of the OSPF standard.
