Minutes to Hours Converter
Enter any number of minutes and get the result in decimal hours, hours-and-minutes notation, total seconds, days, weeks, and months. The converter also works in reverse: enter hours and it fills in the minutes. A step-by-step breakdown shows every calculation so you can check the math yourself.
Formula
Worked example
90 minutes: 90 / 60 = 1.5 decimal hours. Whole hours = floor(1.5) = 1 h. Remaining minutes = 90 - (1 x 60) = 30 m. HH:MM = 1h 30m. Total seconds = 90 x 60 = 5,400 s. Total days = 90 / 1,440 = 0.0625.
How to convert minutes to hours
The conversion is a single division: hours = minutes / 60. Because there are exactly 60 minutes in one hour, dividing any number of minutes by 60 gives you the equivalent decimal hours. For example, 90 minutes / 60 = 1.5 hours, and 45 minutes / 60 = 0.75 hours. To reverse the calculation and convert hours to minutes, multiply by 60: 2.5 hours x 60 = 150 minutes.
Decimal hours vs. HH:MM notation
Decimal hours express time as a single number with a fractional part (for example, 1.5 hours or 2.25 hours). This format is required for most payroll, billing, and spreadsheet calculations because arithmetic is straightforward: 3.25 hours at $20 per hour is simply 3.25 x 20 = $65. HH:MM notation (for example, 1:30 or 2:15) is the familiar clock format used in schedules and timesheets. Converting 1.5 decimal hours to HH:MM: the whole-number part is 1 hour, and 0.5 x 60 = 30 minutes, giving 1h 30m. This calculator produces both formats at once so you always have the right one to hand.
Converting minutes to larger time units
The same logic extends to other time units. To get days, divide minutes by 1,440 (the number of minutes in a day: 60 x 24). To get weeks, divide by 10,080 (1,440 x 7). To get an approximate month count, divide by 43,800, which uses an average month of 365 days / 12 = 30.417 days. These conversions are useful for project planning: knowing that a 3,000-minute task equals roughly 2.08 days or 0.30 weeks gives a clearer sense of scale than the raw minute figure.
Practical uses for a minutes-to-hours converter
Freelancers and consultants track time in minutes and bill in decimal hours. Fitness and coaching apps log workout durations in minutes that need to be summarised as hours for weekly reports. Manufacturing and logistics systems calculate machine run times and flag overtime by converting total minutes to hours. Students and exam-takers convert study sessions: 150 minutes equals 2.5 hours, making weekly totals easier to compare. Programmers converting timestamps stored as minutes into human-readable time strings also rely on the same minute / 60 relationship.

Frequently asked questions
How many hours is 90 minutes?
90 minutes is 1.5 hours. Divide 90 by 60 to get the decimal: 90 / 60 = 1.5. In hours-and-minutes notation that is 1h 30m.
How do I convert minutes to hours for payroll?
Divide the total minutes by 60 to get decimal hours, then round to two decimal places if needed. Multiply by the hourly rate to get the pay amount. For example, 97 minutes / 60 = 1.6167 hours, rounded to 1.62 hours. Most payroll systems accept this decimal format directly.
What is 1 hour and 30 minutes in decimal?
1 hour and 30 minutes is 1.5 decimal hours. Convert the minutes part (30) to a fraction of an hour (30 / 60 = 0.5) and add it to the whole hours (1 + 0.5 = 1.5).
How many minutes are in a day?
There are 1,440 minutes in a day (60 minutes per hour x 24 hours). Dividing any minute count by 1,440 gives you the equivalent number of days.
How do I convert minutes to hours and minutes (not decimal)?
Divide the total minutes by 60 and take the whole-number part as hours. Then subtract that whole number of hours-worth of minutes from the original total to find the leftover minutes. For example, 155 minutes: 155 / 60 = 2.583, so 2 whole hours, and 155 - (2 x 60) = 35 leftover minutes, giving 2h 35m.
How many hours is 120 minutes?
120 minutes is exactly 2 hours (120 / 60 = 2.0). In HH:MM notation that is 2h 00m.
What is 45 minutes as a fraction of an hour?
45 minutes is 0.75 hours, or three-quarters of an hour. Calculation: 45 / 60 = 0.75.
