Precision of measurement describes how exact, reliable and repeatable unit used to measure something.
\The measurement is 14 meters. The units are in meters. \
The measurement is precise to within 0.5 meter.
\So, a measurement of 14 meters could be between (14 – 0.5 = 13.5) 13 .5 meters and (14 + 0.5 = 14.5) 14 .5 meters.
The measurement is precise to within 0.5 meter.
\A measurement of 14 meters could be between 13 .5 and 14 .5 meters.
