Is the accuracy of a gage the same as its resolution?

No. Accuracy is different from resolution and in precision measurement it is important to know what they both are. The resolution of a gage is the degree to which the output of measurement can be broken down, whether in decimal places, parts, divisions, or counts. The smaller degree to which a gage is capable of making a measurement, the higher its resolution. Alternatively, accuracy is how close the output of a measurement is to the actual true value of the measurement. In other words, the less error there is in a particular measurement, the higher the accuracy of that measurement. A high functioning gage requires both resolution and accuracy—you need one to have the other.
