microstrain
Strainexact by definition
One micrometre of extension per metre of length: microstrain, written µε. It equals one part per million, and it is what strain gauges read.

Where the unit came from
A foil strain gauge resolves about one microstrain, and working strains in steel and concrete run from tens to a few thousand of them, so the unit was chosen to make the instrument's output a readable whole number. Yield in mild steel is roughly 1200 µε.
