Time & Decimal Converters
Instant, high-precision conversion tools for payroll calculations: time-to-decimal, decimal-to-minutes, 24-hour military time, FLSA 7-minute rounding rules, and elapsed time intervals.
Time to Decimal Calculator
Convert standard hours and minutes (HH:MM) into exact decimal hours for automated wage and payroll software multiplication.
Decimal to Minutes Calculator
Convert decimal hours (e.g. 7.75 hrs) into clean hours, minutes, and seconds (7 hrs 45 mins) with step-by-step math.
Minutes to Decimal Chart
Complete interactive 1-to-60 minute payroll reference table with instant real-time search filtering.
Military Time Converter
Convert standard 12-hour AM/PM timestamps to 24-hour military format (0000–2400) and NATO phonetic pronunciation.
Hours Between Two Times
Calculate total elapsed time between two clock timestamps with lunch deductions, overnight handling, and decimal breakdown.
Time Duration Calculator
Add, subtract, and sum multiple time duration rows (HH:MM:SS) for multi-task project tracking and payroll audit logs.
7-Minute Rounding (FLSA)
Simulate statutory 15-minute quarter-hour rounding (1–7 min down, 8–14 min up) to verify legal rounding neutrality.
How Do You Convert Sexagesimal Minutes to Decimal Hours for Payroll?
To convert sexagesimal (base-60) minutes into decimal (base-10) hours for payroll, divide the number of minutes by 60: Decimal Portion = Minutes ÷ 60. Add this result to the whole integer hours. For example, 45 minutes divided by 60 equals 0.75 hours, making an 8-hour 45-minute shift equal to 8.75 decimal hours.
Why Is Decimal Time Conversion Mandatory for Payroll Systems?
Accounting and payroll software cannot directly multiply base-60 sexagesimal timestamps by hourly pay rates without causing severe rounding errors. Multiplying 8 hours 30 minutes as $8.30 \times \$20.00$ produces an erroneous $166.00, whereas converting to 8.50 decimal hours yields the accurate statutory gross wage of $170.00.
Frequently Asked Questions Regarding Time Converters
What is the 7-minute rounding rule under federal FLSA law?
Under 29 CFR § 785.48(b), employers using 15-minute timecard rounding must round punches between 1 and 7 minutes down to the nearest quarter hour, and punches between 8 and 14 minutes up to the next quarter hour.
How do I convert military 24-hour time to standard 12-hour AM/PM?
For hours 1300 to 2359, subtract 1200 and append PM (e.g., 1730 becomes 5:30 PM). For hours 0100 to 1159, retain the hour and append AM (e.g., 0830 becomes 8:30 AM). Hour 0000 represents 12:00 AM Midnight.
