Payroll runs on decimals. Convert any minutes to decimal hours, convert back, and keep the complete 1–60 chart that payroll departments pin to the wall.

Decimal hours exist for one reason: you cannot multiply "8 hours 30 minutes" by a pay rate, but you can multiply 8.50 × $20. The conversion is minutes ÷ 60, rounded to two decimal places — the convention used by the standard published payroll charts. The quarter hours are the anchors worth memorising: 15 min = 0.25, 30 min = 0.50, 45 min = 0.75.
Two traps to avoid: 0.50 is half an hour (30 minutes), not 50 minutes; and decimal values are rounded, so a week of daily decimals can differ from exact time by a minute or two — payroll systems accept this, and the Time Card Calculator shows both formats side by side so you can compare.
One shift in, one exact answer out: hours and minutes, decimal hours, break handling, rounding and the gross pay for that shift.

15 minutes. The quarter-hour anchors are 0.25 = 15 min, 0.50 = 30 min, 0.75 = 45 min and 1.00 = 60 min.
Because pay is hours × rate. Decimals make that a single multiplication and standardise rounding across thousands of punches; timesheets then display h:mm for humans and decimals for the payroll system.
No — 8.5 hours is 8 hours 30 minutes. The digits after the point are hundredths of an hour, not minutes. This is the single most common timesheet reading mistake.
Payroll cannot multiply “8 hours 30 minutes” by a rate, so minutes are converted into a decimal fraction of an hour. This converter follows the standard published payroll chart convention: divide the minutes by 60 and round to two decimal places. The minutes box covers the minutes part of an hour (0–60). The reverse box runs the conversion backwards — split a decimal into whole hours and minutes — and the page also counts how many whole quarter-hours (15-minute blocks) a minutes value contains.
Enter 47 minutes and the converter shows 0.78 decimal hours — 47 ÷ 60 = 0.7833…, rounded to 0.78 by the chart convention — and counts 3 quarter-hours in 47 minutes. In the reverse box, 7.58 hours becomes 7:35: the whole 7 hours carry over, and 0.58 × 60 = 34.8 rounds to 35 minutes. At $20 an hour, that 47-minute task is worth 0.78 × $20 = $15.60 of pay.
Convert only the minutes part, then add the whole hours back: 15 minutes is 0.25, so 1 hour 15 minutes is 1.25 hours. The same method scales to any time — 2 hours 47 minutes is 2 + 0.78 = 2.78 hours.
Because 47 ÷ 60 = 0.78333… never terminates. Payroll charts round to two decimal places, and this converter does the same, so a converted value can be off by under half a minute. Across a full week those small roundings can add up to a minute or two — payroll systems accept this as the standard convention.
Many employers round punches to the nearest 15 minutes, so payroll thinks in quarter-hour blocks: 0.25, 0.50, 0.75, 1.00. The quarter-hour count on this page tells you how many of those blocks a minutes value rounds to — 47 minutes is 3 blocks, i.e. 45 rounded minutes.
75 minutes — 1 hour plus 0.25 × 60 = 15 minutes, shown as 1:15 by the reverse converter. The anchor quarters are worth memorising: 0.25 = 15 min, 0.50 = 30 min, 0.75 = 45 min.
