Hours to Minutes Calculator
Turn hours and minutes into a single total of minutes. Useful for timesheets, shift logs, and billing. Free and instant.
Hours & Minutes → Total Minutes
total minutes = (hours × 60) + minutes
How to convert hours to minutes
There are 60 minutes in one hour. To convert, multiply the hours by 60 and add any extra minutes:
total minutes = (hours × 60) + minutes
Decimal hours work too. 1.25 hours means 1 hour and 0.25 of an hour (15 minutes), so it equals 75 minutes. The calculator above handles both whole and decimal hours.
When minute totals are the right format
Payroll runs on decimal hours, but plenty of other systems run on plain minutes. Phone screen-time reports, project timers, kitchen timers, and many scheduling apps all report a count of minutes, so to compare a 25-minute task against a 1.75-hour block you need them in the same unit.
Minutes are also the safest unit for adding things up, the same way cents are safer than dollars. A week logged as 450, 420, 465, 480, and 390 minutes adds to 2,205 minutes, which divides back to 36.75 hours exactly. No fractions are lost along the way.
Checking a minute total against a timesheet
If your timesheet says 7.75 hours and your timer says 452 minutes, something is off: 7.75 × 60 = 465, not 452. The gap of 13 minutes usually means a missed break subtraction or a timer that was left running. Converting both sides to minutes makes the discrepancy visible in seconds.
When you need the number to move in the other direction, the minutes-to-hours converter divides by 60 and formats the result for payroll.

Frequently asked questions
What is 1.5 hours in minutes?
1.5 hours = 90 minutes, because 1 hour is 60 minutes and 0.5 hour is 30 minutes (60 + 30 = 90). Enter 1.5 above to confirm.
How many minutes are in 2 hours 15 minutes?
2 hours 15 minutes = 135 minutes (2 × 60 = 120, plus 15 = 135). Enter 2 and 15 in the converter.
How many minutes are in 8 hours?
8 hours = 480 minutes (8 × 60). This is the length of a standard full-time shift without a lunch break.
Why convert hours to minutes?
Some timesheets, billing systems, and scheduling tools record time in minutes. Converting makes it easy to add up a day or a week of work, and minute totals are what most time clocks store internally.
How many minutes are in a full work week?
A 40-hour week is 40 × 60 = 2,400 minutes. A 37.5-hour week is 2,250 minutes. These totals are useful when a scheduling app or a phone timer reports your week in minutes.
How do I convert decimal hours like 7.75 into minutes?
Multiply by 60: 7.75 × 60 = 465 minutes. The whole part (7 hours) contributes 420 minutes and the 0.75 contributes 45.
How do I go from minutes back to hours?
Divide by 60. 465 minutes ÷ 60 = 7.75 hours. If you want hours and minutes instead of decimal hours, note that 465 = (7 × 60) + 45, so it is 7 hours 45 minutes.
Why are there 60 minutes in an hour anyway?
Blame the Babylonians. Their counting system was base 60, and 60 divides cleanly by 2, 3, 4, 5, 6, 10, 12, 15, 20, and 30, which made fractions of an hour easy to work with before decimals existed.
How many minutes are in 7.5 hours?
7.5 × 60 = 450 minutes. This is the paid length of a standard 8-hour day with a 30-minute unpaid lunch, which is why 450 shows up so often on scheduling reports.
How many minutes are in a month of full-time work?
About 160 hours per month (2,080 ÷ 12), which is 9,600 minutes. Payroll systems use the 2,080-hour year (52 weeks × 40) as the baseline, so monthly totals drift slightly depending on where the weeks fall.
