Minutes to Decimal Converter
Convert h:mm to decimal hours for payroll and back — quarter-hour rounding and a full conversion table included.
Examples
Timesheet entry to payroll decimal
7:457.75 decimal hours45 minutes ÷ 60 = 0.75, so seven-and-three-quarter hours is written 7.75 in payroll software.
Odd minutes to decimal
22 minutes0.37 decimal hours22 ÷ 60 = 0.3666…, rounded to two decimals — the 0.01-precise mode's answer for any minute value.
Decimal back to h:mm

About this tool
Minutes to Decimal Converter is built around one conversion that payroll runs on: 7:45 becomes 7.75. Payroll systems — ADP, QuickBooks, Gusto, and most in-house software — do not accept 7:45 in a hours-worked field, because wages are computed as decimal hours × hourly rate. This tool converts h:mm to decimal hours and, just as importantly, back again: type 7.75 and read 7:45, or enter 0.37 to see that it is 22 minutes. Both fields are live, so whichever format you have in hand, you type it and the other appears.
The math is a single division: minutes ÷ 60. A 45-minute task is 45 ÷ 60 = 0.75 hours; 22 minutes is 22 ÷ 60 ≈ 0.37 hours. The reverse multiplies by 60 and rounds to the nearest whole minute, which is exactly reversible for values that came from real clock times. Negative values are accepted on purpose — a payroll correction such as −0.5 hours (−30 minutes) is a real entry in correction runs, and the tool formats it as −0:30 rather than refusing it.
Because timesheet policies differ, rounding is yours to choose. The 0.01-precise mode gives plain two-decimal minutes-to-hours math; the quarter-hour mode rounds to the nearest 0.25, the standard 15-minute granularity many employers use (7:20 → 7.25, 7:50 → 7.75). Below you will find a full minutes-to-decimal chart for 1–60 minutes with copyable rows — the same numbers payroll administrators keep on a desk reference — in 5-minute steps by default or every minute with one click.
Conversions happen entirely in your browser. Pay figures are sensitive, and there is no reason any of them should touch a server: nothing is uploaded, nothing is logged, and the tool works offline. Your input is saved only in your own browser between visits and can be wiped with one click, so yesterday's timesheet does not linger anywhere you cannot reach.
What this tool does not do
- The chart covers 1–60 minutes; larger values go through the converter fields directly.
- Two-decimal output follows the minutes ÷ 60 convention; it is a math tool, not advice on which rounding policy your jurisdiction allows.
- Seconds are not handled — minute precision is the payroll standard this tool targets.
How to use this tool
Enter what you have
Type an h:mm time like 7:45 or a decimal like 7.75 — the other field converts immediately in whichever direction you need.
Pick the rounding
Leave 0.01-precise for exact two-decimal values, or switch to quarter-hour (0.25) for standard 15-minute timesheet rounding.
Read the result
The result card shows the converted value, the exact minutes behind it, and which rounding applied — e.g. 7:45 → 7.75 h, 465 minutes.
Copy from the table
Use the payroll conversion table for 1–60 minutes: copy a single row or the whole chart to keep next to your timesheet.
Use cases
Filling in payroll software
Turn clock times like 8:07 into the decimal hours (8.12) the hours-worked field actually expects, in either rounding policy.
Checking a pay stub
Read 7.75 hours on a pay stub and confirm it is 7:45 of worked time — or reverse-check that 0.37 really is 22 minutes.
Freelance invoices
Sum client work in minutes and invoice in decimal hours with quarter-hour rounding, using the chart as the desk reference.

Common mistakes
Mistake:Reading 7:30 as 7.30 decimal hours.
Fix:30 minutes is half an hour, so 7:30 is 7.50 decimal hours. The colon is minutes, the dot is a fraction of an hour — this tool exists to translate between the two without that slip.
Mistake:Typing 1:60 for one and six-tenths hours.
Fix:Colon notation is base-60: 1:60 does not exist. 1.6 decimal hours is 1:36; one hour and sixty minutes is just 2:00.
Mistake:Assuming quarter rounding is what your employer does.
Fix:Policies vary: some round to the nearest 15 minutes, some use the 7/8 rule, some pay exact minutes. Check the policy first, then pick the matching rounding mode here.
Frequently asked questions
What is 7:45 in decimal hours?
7.75. Divide the minutes by 60 (45 ÷ 60 = 0.75) and add the hours: 7 + 0.75 = 7.75. This is the value payroll software expects in an hours-worked field — enter 7:45 in the tool and 7.75 appears in the decimal field immediately, in whatever rounding mode you have selected.
How do I convert decimal hours back to minutes?
Multiply by 60. The decimal part is a fraction of an hour, so 7.75 × 60 = 465 minutes, which is 7:45; 0.37 × 60 ≈ 22 minutes. The tool runs this direction too: type the decimal in the right-hand field and the h:mm value appears in the left one. Results round to the nearest whole minute.
What is quarter-hour rounding?
It is the convention of rounding worked time to the nearest 15 minutes, i.e. to 0.25 decimal hours: 7:20 becomes 7.25 and 7:50 becomes 7.75. Where an exact tie occurs, this tool rounds up (Math.round behavior); some employers use the stricter federal 7/8-minute rule instead, so always check your own payroll policy. The rounding selector switches between 0.01-precise and quarter-hour output.
Why does payroll software use decimals instead of h:mm?
Because wages are computed as decimal hours × hourly rate. Multiplication only works cleanly in base-10: 7.75 hours at $20/h is $155.00, while 7:45 × 20 in base-60 notation is meaningless to a computer. Converting minutes to decimals once — at data entry — keeps every later calculation in plain decimal arithmetic.
Is my data stored anywhere?
Not on any server. The conversion runs in your browser, and nothing is uploaded or logged. Your current input is kept in your own browser's local storage so it survives closing the tab — that copy never leaves your device, and the Clear button (or Reset) wipes it. In private browsing windows nothing persists at all.
