Alternative Units of Measurement

[wrapper]

I was just diverted through a chain of events to this Wiki page of Units of measurement. A few are just humorous, e.g.

New York Second
The New York Second (“the shortest unit of time in the multiverse”) is defined as the period of time between the traffic lights turning green and the cab behind you honking.[40] The idiomatic expression “in a New York minute”, used in various contexts to mean an instant or a very short time, is of similar origin, referring to the busyness of New York and impatience of its residents.

Some are deep :

Microcentury
According to Gian-Carlo Rota,[35] the mathematician John von Neumann used the term microcentury to denote the maximum length of a lecture. One microcentury is 52 minutes and 35.69 seconds – one millionth of a century.
