Verified July 25, 2026How we fact-check

Summary

We checked the chart’s arithmetic identity (minutes ÷ 60), rounding at 2 and 3 decimal places, and the boundary claim that 29 CFR §785.48 punch rounding is out of scope. All checked claims are marked Verified.

This tool has no statutory rate constants. Accuracy is pure arithmetic plus disclosed rounding. Verification result: ready to publish for the stated conversion and chart scope.
