Math: Traffic engineering: Unit: Erlang: What is the Erlang unit of 
traffic? [telephone]

The Erlang unit of traffic is defined as
(e.g. specific for telephone calls)
 (total amount of calls per time unit) . (average time per call)   (1)

e.g.                                                               (2)
total amount of calls per time unit = 80 calls per hour
average time per call = 10 minutes = 10/60 hour = 1/6 hour
Putting (2) in (1) gives:
 80 . (1/6)
= 80 / 6
= 13.33... Erlang
