Fact Check: Minutes to Decimal Hours Converter

Verified July 25, 2026How we fact-check

Summary

We checked the converter's arithmetic identity (minutes ÷ 60), rounding behavior at 2 and 3 decimal places, reverse conversion to whole minutes, HH:MM parsing rules, 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 scope.
