Decimal Time Converter (Payroll Hours)
Decimal time converts hours and minutes into a single decimal number — the standard for payroll, time tracking and billing. 7 hours 30 minutes becomes 7.50 hours; 14:30 becomes 14.50. Payroll systems require decimal hours because decimal arithmetic is exact, whereas "7:30 + 3:45" is error-prone.
This converter takes any clock time and returns decimal hours (14.50 for 14:30) and decimal minutes (870 total minutes). It is the quickest way to fill out a time card or verify a payroll export.

When to Use Decimal Time (Payroll Hours)
Payroll calculation
Convert clock-in/clock-out times to decimal hours before multiplying by the hourly rate. 8:15–16:45 = 8.50 hours, not "8:30".
Time tracking & billing
Freelancers and agencies bill in decimal hours or tenths. Convert session times so invoices match the time tracking tool.
Timesheet export verification
When exporting timesheets to payroll software, spot-check that 7:30 exported as 7.50 — a common off-by-error source in integrations.
Frequently Asked Questions
What is 7:30 in decimal hours?
7:30 = 7.50 hours. The rule: divide minutes by 60 and add to hours — 30 ÷ 60 = 0.50, so 7 + 0.50 = 7.50.
How do I convert minutes to decimal?
Divide the minutes by 60: 15 min = 0.25, 30 min = 0.50, 45 min = 0.75. 20 minutes = 0.33 hours.
Why does payroll use decimal time?
Payroll software multiplies hours by a rate; decimal hours keep the math exact and auditable, while "hours:minutes" requires error-prone conversion at every step.
What is the difference between decimal time and metric time?
Decimal time here means decimal hours (a day still has 24 hours). Metric decimal time (proposed) would split the day into 10 hours — a different, non-payroll concept.
