A flick is a unit of time equivalent to exactly 1/705,600,000 of a second. The figure was chosen so that frequencies of 24, 25, 30, 48, 50, 60, 90, 100 and 120 Hz, as well as 1/1000 divisions of all those, can be represented with integers.[1] The unit was launched in January 2018 by Facebook.[2] A flick is approximately 1.42 x 10−9 s, which makes it larger than a nanosecond but much smaller than a microsecond.
