tolerance
tolerancia
the largest amount a measurement is allowed to differ from its target value, often written with \pm.
Example
A pin made to 2.5 \pm 0.05 in has a tolerance of 0.05 in, so it must measure from 2.45 to 2.55 in.
In Spanish
tolerancia — la mayor diferencia permitida entre una medida y su valor objetivo; muchas veces se escribe con \pm.
Un perno hecho a 2.5 \pm 0.05 in tiene una tolerancia de 0.05 in, así que debe medir de 2.45 a 2.55 in.
