GUM (Guide to the Expression of Uncertainty in Measurement)

The GUM (Guide to the Expression of Uncertainty in Measurement) is an international standard that provides a systematic way to evaluate and communicate the confidence in measurement results. It helps professionals quantify the possible errors or variations in measurements, ensuring transparency and reliability. By identifying sources of uncertainty and estimating their impact, GUM enables meaningful comparison of measurements, supports quality control, and fosters trust in scientific and technical results. Essentially, it offers a clear framework to express how precise or accurate a measurement is, considering all potential factors that could influence the outcome.
