Gauge factor (GF) or strain factor of a strain gauge is the ratio of relative change in electrical resistance R, to the mechanical strain ε. The gauge factor is defined as: $${\displaystyle GF={\frac {\Delta R/R}{\Delta L/L}}={\frac {\Delta R/R}{\varepsilon }}=1+2\nu +{\frac {\Delta \rho /\rho }{\varepsilon }}}$$ See more It is a common misconception that the change in resistance of a strain gauge is based solely, or most heavily, on the geometric terms.
