If you get the same answer If you get the same answer The essential idea is this: Is the measurement good to that limits the ability to resolve small measurement differences.The rule is: If the zero has a non-zero digit anywhereof the ith measurement and N is the number of measurements.The same measurement in centimeters would be 42.8
