Even with the best measuring apparatus available,you can rarely get an absolutely exact measurement of anything. The readings you get will almost always be either a little bit larger or smaller than the precise length or pressure or whatever you are trying to measure.
If you make a lot of measurements, the calculated average or mean of your measurements will come close to the exact measurement, but you still have to report the error or the range of variations in your measurements around the mean. This enables others to see how reliable your measurements are, particularly if they are being used in combination with other measurements, for example, using length and breadth to estimate an area of a rectangle.
