FIVE BY FIVE means that everything is fine, clear, or operating at 100% efficiency. When someone says "everything is five by five," they are expressing that a situation is completely in order, on track, and free of issues.
Origin
.
The phrase originates from mid-20th-century radio communications. Operators evaluated transmissions using two scales from 1 to 5.
.
Signal Strength: Measured on a scale of 1 (faint) to 5 (strong).
.
Signal Clarity: Measured on a scale of 1 (unclear/garbled) to 5 (perfectly clear).
.
A score of "5 by 5" meant maximum signal strength and maximum clarity, equivalent to hearing someone "loud and clear."
.
Popular Culture
.
Over time, military and radio jargon crossed over into mainstream pop culture to mean "everything is good" or "A-OK".
.
In my work, it functions as a title series and an expression of denial and a covering for what lies underneath.
