Scientists have no choice but to use steps of the 3rd power beyond milli- and kilo- because intermediate prefixes do not exist, however it is perfectly acceptable to use centi-, deci-, deca- and hecto- with any SI unit.
Jiffy is not an officially designated time period and means different time intervals depending upon its application, e.g.
In computing, the duration of one tick of the system timer interrupt. Typically, this time is 0.01 seconds.
In physics, the time taken for light to travel one centimetre (sometimes one foot, or sometimes the width of a nucleon)
In electronics, the time between alternating current power cycles (1/60 or 1/50 of a second)
It has also been used for millisecond and nanosecond and very likely for other intervals.
