Jiffy?
Jiffy?
(OP)
I heard on the radio this morning that a jiffy is equal to a power cycle period at 50 or 60 Hz, among other definitions. Completely new to me. Web searches take me to http://www.numericana.com/answer/units.htm#jiffy where it suggests the more modern electrical engineering definition is 10 ms, but with no source given. Before I email Fred Berman, Ph.D., P.E. asking him for his source, I thought I'd ask here. Anyone hear of these definitions, and if so, where?

I.e., it can be whatever you want it to be.

I actually thought Europe had a monopoly on weird names for units of measurement and had used most of them while devising the CGS system, but perhaps this is a late challenge from the colony.

If there was no electricity there would be no internet. Good point, don´t you? :D

Below is a link to a little more scientific site at the University of North Carolina-Chapel Hill which has definitions for units of measure. It gives some insight as to where the unit may have come from.
