A measurement is considered precise when it yields consistent and reproducible results under the same conditions, regardless of whether those results are close to the true value. This means that repeated measurements will show little variation from each other, indicating a high degree of reliability in the measurement process. Precision does not necessarily imply accuracy; a precise measurement can still be systematically off from the actual value.
What determines how precise a measurement is
It is precise if it is repeatable.
Is as exact as possible

The precise measurement is 5.7 mm for the first value and 3.6 m for the second value.

when it has either been witness or confirmed by a governing body or official.
The measurement 25.81 is precise to the nearest hundredth.
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.
