In a standard ruler, the markings at .5 cm show up clearly -- but let's say you can get a little bit closer than that. If it looks like you can get about within .3 cm of an accurate measurement, then your uncertainty is .3 cm.

WebbIn statistical parlance, the term “uncertainty” is associated with a measurement where it refers to the expected variation of the value, which is derived from an average of several readings, from the true mean of the data set or readings. In other words, the uncertainty can be considered as the standard deviation of the mean of the data set.
