.5cm/.5cm/.005g
This value is variable and different for each type of measurement. The error can be absolute or relative. A measurement without any error doesn't exist.
The precision of integers with trailing zeros is ambiguous. The precision of 20400 litres can be 1, 10 or 100. Corresponding to these values, the greatest possible errors can be 0.5L, 5L or 50L. Actually, the precision could even be 20400L, in which case the maximum possible error is 10200L. If, for example, you had tanks of 20400L each, you might simply know how many tanks' worth you had - precision to 20400L. Unlikely, though.
A good way to reduce error or increase measurement accuracy is to take several measurements and compute their average. In other words, you achieve accuracy through averaging. (This also validates the repeatability of the measurement.)

Several observations are taken for each measurement to eliminate or decrease the margin of error.

Answer #1:Probably a job that uses lots of measuring. Like a contractor or maybe a physicist.==========================================Answer #2:"Probably" is a sure sign of a non-answer.Any job that involves assembling mechanical components or parts.Example:One department of your company makes open metal boxes, and anotherdepartment makes covers for the boxes. Your designers had better makesure that when each item is manufactured with the greatest possible error(but still within spec) in opposite directions, that the covers will still fit onthe boxes.(Been there, seen that. They didn't. It wasn't pretty.)
