no only if it is precise it is accurate
Certainly. Precision and accuracy do not mean quite the same thing. All measuring tools need to be recalibrated from time to time against a standard. For instance you can get a very precise reading from a micrometer or vernier gage but if it has not been correctly calibrated the reading will not be accurate.
Digital weight scales have been proven to be very accurate. The way in which they work is by measuring the change in resistivity of the wires that are inside of them when a weight is placed upon them. This technique for measuring weight is very accurate and very precise. If you are looking for a scale with accuracy within .005 of an ounce, then digital is the way to go.
It depends on the measuring instrument that you use (including its calibration), how careful you are, how many measurements you take, whether or not you have allowed for external factors that could affect your measurement.
It is not; there are more precise measurements.
