Measurement Uncertainty Calculator
Estimate the expanded measurement uncertainty of your instrument using the GUM (JCGM 100:2008) approach.
u = r / (2√3)
u = U / 2
u = s / √n
u = a / √3
u = a / √3
This tool is for preliminary assessment only. The official measurement uncertainty is stated on the certificate using accredited methods and actual measurement data.
