Can someone explain to me the greatest possible error when finding the maximum and minimum possible lengths of something?? PLEASE!!!

• Math -

The error can be expressed as units, or as percentage.

Say you have a somewhat accurate ruler, and you measure a board. You find a length of 3m, but the lines on the ruler are rather blurred, so there's a chance of a 2mm error either way.

So, the actual length could be anywhere from 2.998m to 3.002m.

Or, if you're using an electronic device, maybe its specs say that it's accurate to 1%.

In this case, 1% of 3m = 3cm, so the real length could be from 2.97m to 3.03m.
