Accuracy is the proximity to the true value. Compared to the metric scale, the vernier provides more accurate measurements and has a lower number. A micrometer is more accurate than a vernier. If the vernier calibration is incorrect or if the measurement operator does not know/verify the zero offset, the measurement will not be accurate.
