It depends on the measuring instrument that you use (including its calibration), how careful you are, how many measurements you take, whether or not you have allowed for external factors that could affect your measurement.

It is precise if it is repeatable.

The precise measurement is 5.7 mm for the first value and 3.6 m for the second value.
What determines how precise a measurement is
It is precise if it is repeatable.
The measurement 25.81 is precise to the nearest hundredth.
Yes, a measurement can be precise without being accurate. Precision refers to how close repeated measurements are to each other, while accuracy refers to how close a measurement is to the true value. It is possible for measurements to be consistently close to each other (precise) but consistently off from the true value (inaccurate).
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.

A measurement in pints is more precise.
