Someone must have felt very clever when they concluded Erlang would be dimensionless. Calls per second X seconds per call = no unit. But that's wrong. Clearly the number of calls ongoing maps on to lines being used for a circuit-switched network, or datagrams in flight, or whatever. Far from dimensionless. Call_starts per second X call.seconds per call_start = calls as the unit Much more plausible, IMHO.
