The margin of error of a measurement is called
What is uncertainty? if it is not stated otherwise, it is half of the precision measuring device used. p. 82 If something is 6 cm long, and the precision would be 1 cm so the uncertainty would be 1/2=0.5 cm. You add and subtract the uncertainty: measured value +- measurement uncertainty so 6cm+- 0.5cm
