Accuracy vs. Precision

Accuracy (правильность измерений) is a measure of rightness or how close a measured value agrees with the correct value. An aircraft tool is accurate if it correctly reflects the size of the unit being measured.

Precision (прецизионность\ воспроизводимость измерений) is the measure of exactness. It refers to how closely each unit of measure agrees with another. A precise tool will get the same measurement each time.

It is important to note that just because an aircraft tool is more precise does not mean it is more accurate and accurate tools do not have to have the best precision. The best tools are those tools that have the precision for the job with a good enough accuracy.
