The Difference Between Accuracy And Precision Measurement In Your Machine Shop
Accuracy in measurement describes how closely the measurement from your system matches the actual or true measurement of the thing being measured. Think of accuracy as the “trustworthiness” of a measurement system.
Precision in measurement describes how well a measurement system will return the same measure; that is its Repeatability.
It is important to be both Accurate and Precise if you are to get useable information from your measurement system.
