Industry-standard calibration calculations — no signup required. Built on the same engine that powers CalibrationOS.
Calculate GUM-compliant expanded uncertainty from Type A and Type B components. Supports rectangular, triangular, and normal distributions with Welch-Satterthwaite effective degrees of freedom.
Determine optimal calibration intervals using the ILAC G24 staircase method. Input your pass/fail history and get a data-driven recommendation to extend, shorten, or maintain your current interval.
Run an AIAG-compliant Gage R&R study using the average and range method. Enter operator, part, and trial measurements to get %GRR, NDC, and a pass/marginal/fail verdict.
These calculators use the same algorithms as CalibrationOS. For automated uncertainty budgets, interval optimization, and MSA studies across your entire equipment inventory — try CalibrationOS free.
