📐 Metrology Term of the Month: Measurement Uncertainty
No measurement is perfectly exact. Measurement uncertainty describes the range of values within which the true value of a measurement is expected to fall.
It can be influenced by factors such as the measuring equipment, environmental conditions, the measurement process, and even the part being measured.
Understanding measurement uncertainty helps metrology professionals determine how much confidence they can place in a measurement result and make better-informed decisions.
In simple terms: it’s not just about the number you measure, but how confident you are in that number.
