Sinificant figures are the number value of an experiment measure that are correctly recorded. For a measurement to be precise it should be estimated one decimal place of the smallest scale. For example, if you are measuring something in centermeters you should estimate to the nearest .01cm.There is such thing as to precise when it comes to measuring, if you are measuring something in mL it is to precise to measure 8.325mL. Accuracy and precise are two different ways to describe the error associated with measurement.Precise is the closeness of measurement that the same quality agree on. Precise measurement is limited by the uncertainty of the measurment of the device. To know if the measurement is precise it may have a +_ before the sinificant figure. Accuracy is how close the measurment value is to an actual or accepted value. the only way to determine accuracy is by comparing the siginificant figure to the "real" value. if the person knows the "real" value.
