How to compute decimal hours
Take the number of minutes and divide by 60, because one hour has 60 minutes. Round the result to two decimals for payroll. For example, 42 minutes divided by 60 is 0.70 hours.
Minutes themselves never change between standard and military time; they always run from 00 to 59 in both systems. This chart is about turning those minutes into decimal hours for timesheets and pay.

Frequently asked questions
How do I convert minutes to decimal hours?
Divide the number of minutes by 60, because one hour contains 60 minutes. For example, 15 minutes is 0.25 hours and 45 minutes is 0.75 hours. Round the result to two decimals for most payroll systems.
What is 30 minutes in decimal hours?
30 minutes is 0.50 hours, because 30 divided by 60 equals one half. This is the single most common payroll conversion.
Why does payroll use decimal hours instead of minutes?
Pay is calculated by multiplying time worked by an hourly rate, and multiplication only works with decimal numbers. Converting minutes to decimal hours first keeps timesheet math simple and consistent.
What is 20 minutes in decimal hours?
20 minutes is 0.33 hours when rounded to two decimals. The exact value is one third of an hour, which repeats, so payroll charts round it.
Is decimal time the same thing as military time?
No. Military time is a 24-hour clock where 1830 means 6:30 PM. Decimal hours express minutes as a fraction of an hour, so 6 hours and 30 minutes worked is written as 6.50 hours. Minutes from 00 to 59 are identical in standard and military time.
