850 yards has (at least) two significant digits so that measure has greater precision
(trailing zeros - when there is no decimal point are always difficult to determine if they are significant or not)
850 has two or three significant figures
850,0 has unequivocally four significant figures
What determines how precise a measurement is
19.2cm is more precise
A measurement in pints 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.

3526 yards is more precise because it provides a more specific measurement than 2 miles, which is a rough estimate.
3 3-16 is more precise. it gets a closer measurement. 1-2 means 0.5 of the unit measurement 3-16 means 0.1875 of the unit measurement
