Below are our specialized reference guides for the most frequently searched minute-to-decimal values. Each page features compound worked examples (e.g. 1 hour 15 min, 2 hours 15 min, etc.), mathematical fractions, and practical payroll rounding rules:

• 10 Minutes in Decimal (0.17 Hours) — One-sixth of an hour, common in six-minute legal billing.
• 15 Minutes in Decimal (0.25 Hours) — Exactly one quarter of an hour, the universal standard billing block.

Payroll Rounding Conventions Under FLSA

Under the Fair Labor Standards Act (FLSA) regulations (29 CFR 785.48), employers may round employee punch times using consistent rounding increments. The most common increments include:

• 7-Minute Rule (Quarter-Hour / 15-Minute Rounding): Time from 1 to 7 minutes rounds down to the nearest quarter hour, while time from 8 to 14 minutes rounds up to the next quarter hour (0.25 hours).
• 5-Minute Rounding: Time rounds to the nearest twelfth of an hour (0.0833 hours).
• 6-Minute Rule (Tenth-of-an-Hour Rounding): Every 6-minute increment corresponds to exactly 0.1 decimal hours.

Using consistent formulas prevents wage theft disputes and ensures that punch discrepancies balance out evenly over pay periods.
