Incorrect 7-Minute Payroll Rounding
Failing to apply the 7/8 rule correctly, leading to non-compliant timecard adjustments under FLSA standards.
Truncating Decimal Digits
Cutting off decimals instead of rounding (e.g. 15 minutes = 0.25 hours, not 0.2).

Frequently Asked Questions
Helpful answers regarding decimal time calculations and billing rules.
How does the Time to Decimal Calculator handle rounding?
Our calculation engine formats results to 2 decimal places by default, applying standard IEEE floating-point precision to ensure exact fractional accuracy.

Law firms divide one hour into 10 six-minute increments (0.1 hours each). This makes multiplying hourly rates by billable time clean and standardized.
