No. Accurate relates to how close the actual measurement the instrument measures. Precise relates to how much detail the instrument gives when measuring. They are independent to each other: An measurement can be precise and accurate (eg the value of π is 3.141592654) An measurement can be precise and inaccurate (eg the value of π is 1.733677432) An measurement can be less precise and accurate (eg the value of π is 3.14) An measurement can be less precise and inaccurate (eg the value of π is 1.73).

An automatically measurement has a higher precision than a manually measurement.
19.2cm is more precise

The precision of a measurement can be determined by looking at the number of decimal places in the measurement. The more decimal places, the more precise the measurement. Additionally, if a measuring tool is capable of measuring smaller increments, it can provide a more precise measurement.
