Minutes to Hours Converter
Convert minutes to decimal hours (min to h) for timesheets and payroll
1 minute = 1/60 hour ≈ 0.016667 hours. To convert minutes to hours, divide the minutes by 60, so 90 minutes = 1.5 hours and 45 minutes = 0.75 hours.
How to convert minutes to hours
An hour is exactly 60 minutes, a convention inherited from the base-60 counting of ancient Mesopotamia. To turn minutes into hours you ask how many 60-minute blocks they fill, which is division by 60. The answer comes out in decimal hours: 90 ÷ 60 = 1.5, meaning one and a half hours. The hours to minutes converter multiplies by 60 to reverse it, and the time converter handles every unit from nanoseconds to years.
That decimal is the source of most confusion. 1.5 hours is 1 hour 30 minutes, not 1 hour 50 minutes, because the .5 is half of an hour, not 50 minutes. Timesheets and payroll software want the decimal form, because you can multiply it by an hourly rate; clocks and schedules want hours and minutes. This page covers both. For shorter spans, the seconds to minutes converter works the same way.
Step by step
- Take the number of minutes.
- Divide by 60 to get decimal hours.
- For hours and minutes, keep the whole hours and multiply the decimal part by 60.
- For payroll, round to two decimal places or as your employer's policy says.

Worked examples
A 45-minute meeting, a 90-minute movie, and 135 minutes of overtime to enter on a timesheet.
45 min ÷ 60 = 0.75 h
= 0.75 h
90 min ÷ 60 = 1.5 h
= 1.5 h
135 min ÷ 60 = 2.25 h
= 2.25 h
How do you convert minutes to hours and minutes?
Divide by 60: the whole-number result is the hours and the remainder is the minutes, so 135 minutes is 2 h 15 min, because 2 × 60 = 120 leaves 15.
On a calculator that only shows decimals, divide by 60, note the whole number, subtract it, and multiply what is left by 60. For 135 minutes: 135 ÷ 60 = 2.25, keep the 2, and 0.25 × 60 = 15 minutes.
| Minutes | Hours and minutes | Decimal hours |
|---|---|---|
| 95 min | 1 h 35 min | 1.5833 h |
| 145 min | 2 h 25 min | 2.4167 h |
| 330 min | 5 h 30 min | 5.5 h |
| 517 min | 8 h 37 min | 8.6167 h |
| 745 min | 12 h 25 min | 12.4167 h |
In a spreadsheet the same split is =INT(A2/60) for the hours and =MOD(A2,60) for the minutes. Use the h:mm answer for schedules and the decimal answer for anything you multiply, such as pay.
Why do some minutes give repeating decimals in hours?
Because 60 contains the factor 3, any minute count that is not a multiple of 3 becomes a repeating decimal: 20 minutes is 0.3333… hours and 10 minutes is 0.1666… hours.
A fraction ends cleanly in decimal only when its reduced denominator is built from nothing but 2s and 5s, the factors of 10. Sixty is 2 × 2 × 3 × 5, so the 3 has to cancel. It does for 3, 6, 9, 12 and every other multiple of 3, which is why 6 minutes is exactly 0.1 h and 27 minutes is exactly 0.45 h.
Of the 59 minute values from 1 to 59, only 19 convert exactly; the other 40 repeat forever. That is why payroll systems round to two decimals, and why the timesheet chart on this page also lists four-decimal values.
The rounding is small but real: entering 20 minutes as 0.33 h drops 12 seconds each time, so keep fractions exact until the final total. Computers meet the same problem in base 2, where even 0.1 has no exact binary form; the decimal to binary converter shows how base-2 place values work.

Minutes vs hours: what is the difference?
A minute is one sixtieth of an hour, and both units are defined from the SI second. The first rows are generated from the unit data; the rows below show how each unit behaves on clocks, timesheets and pay records.
| Attribute | Minutes | Hours |
|---|---|---|
| Symbol | min | h |
| System | Accepted with SI | Accepted with SI |
| Defined as | 60 s | 3,600 s |
| One unit equals | 0.016666667 h | 60 min |
| Share of a day | 1/1,440 | 1/24 |
| On a timesheet | Converted to hundredths of an hour | Entered as decimals, such as 7.80 |
| Rounding allowed by 29 CFR 785.48 | To the nearest 5 minutes | To the nearest tenth or quarter of an hour |
| Highest value on a clock | 59, then the hour rolls over | 23 on a 24-hour clock, 12 on a 12-hour clock |
4 key differences
- Every minute adds 0.016667 h to a decimal-hour total, so 7 hours 12 minutes is 7.2 hours.
- A day contains 1,440 minutes but only 24 hours.
- US federal rules let employers round punch times to the nearest 5 minutes, or to the nearest tenth or quarter of an hour, provided the rounding averages out over time.
- Sixty divides evenly by 2, 3, 4, 5, 6, 10, 12, 15, 20 and 30, so halves, thirds, quarters, fifths and sixths of an hour are all whole minutes.
Minutes to decimal hours chart for timesheets (1–60 minutes)
Payroll and billing systems record time in hundredths of an hour. Find the minutes past the hour in the left column and add the decimal to the whole hours. For example, 7 hours 38 minutes is 7 + 0.63 = 7.63 hours.

Decimal hours vs hours and minutes: a payroll example
Suppose you clock in at 8:52 a.m., clock out at 5:10 p.m. and take a 30-minute unpaid lunch. From 8:52 to 17:10 is 498 minutes; minus lunch leaves 468 minutes. Divide by 60: 468 ÷ 60 = 7.8 hours, which is 7 h 48 min. At $22.50 an hour, the day's pay is 7.8 × 22.50 = $175.50.
Now the common mistake: writing 7 hours 48 minutes as “7.48”. At the same rate, 7.48 × 22.50 = $168.30, so the worker is underpaid by $7.20 for the day, or $36.00 over a five-day week. The minutes must always be divided by 60 before they sit after the decimal point.
Quick equivalents to memorize
- 15 min = 0.25 h, 30 min = 0.5 h, 45 min = 0.75 h.
- 6 min = 0.1 h, which is why many firms bill in tenths of an hour.
- 20 min = 0.3333 h and 40 min = 0.6667 h, the two awkward ones.

What is the 7-minute rule for rounding work time?
Under the 7-minute rule, an employer that rounds to the nearest quarter hour drops 1 to 7 minutes past a quarter and counts 8 to 14 minutes as the full quarter hour. Many US employers round punch times to the nearest quarter hour. Under federal rules (29 CFR 785.48) this is allowed only if, over time, it does not consistently shortchange employees. State laws and company policy can differ, so check yours before relying on this table.
| Punch time | Recorded as | Decimal added |
|---|---|---|
| 0–7 minutes past | Round down to the hour (:00) | +0.00 h |
| 8–22 minutes past | Round to :15 | +0.25 h |
| 23–37 minutes past | Round to :30 | +0.50 h |
| 38–52 minutes past | Round to :45 | +0.75 h |
| 53–59 minutes past | Round up to the next hour | +1.00 h |
Long durations: minutes to hours and minutes
For durations longer than an hour, the clock-style answer is often more useful than the decimal. Each row shows both, so you can pick the one your form asks for.
| Minutes | Hours and minutes | Decimal hours |
|---|---|---|
| 61 min | 1 h 1 min | 1.0167 h |
| 75 min | 1 h 15 min | 1.25 h |
| 90 min | 1 h 30 min | 1.5 h |
| 100 min | 1 h 40 min | 1.6667 h |
| 125 min | 2 h 5 min | 2.0833 h |
| 150 min | 2 h 30 min | 2.5 h |
| 200 min | 3 h 20 min | 3.3333 h |
| 250 min | 4 h 10 min | 4.1667 h |
| 300 min | 5 h | 5 h |
| 400 min | 6 h 40 min | 6.6667 h |
| 450 min | 7 h 30 min | 7.5 h |
| 500 min | 8 h 20 min | 8.3333 h |
| 600 min | 10 h | 10 h |
| 1,000 min | 16 h 40 min | 16.6667 h |
| 1,440 min | 24 h | 24 h |
Common mistakes when converting minutes to hours
- Dividing by 100. An hour has 60 minutes, not 100. 30 minutes is 0.5 h, not 0.3 h.
- Reading the decimal as minutes. 2.25 h is 2 h 15 min, not 2 h 25 min.
- Rounding each entry. Rounding every short task to 0.33 h and then adding them drifts. Add the minutes first, then divide once.
- Adding clock times as decimals. 1:45 + 2:30 is 4:15 (255 minutes), not 3.75 or 4.15. Convert each to minutes, add, then divide by 60.
- Forgetting that spreadsheets store time as days. In Excel and Google Sheets a time such as 7:48 is stored as a fraction of a day (0.325). Multiply the cell by 24 to get decimal hours (7.8); if the cell holds plain minutes, divide by 60 instead.

Minutes to hours FAQs
Short, exact answers to what people ask most.
How do you convert minutes to hours?
Divide the number of minutes by 60. For example, 150 minutes ÷ 60 = 2.5 hours, which is 2 hours 30 minutes.
What is 45 minutes in hours?
45 minutes is 0.75 hours, or three quarters of an hour. On a timesheet you would enter 0.75.
How do I convert minutes to decimal hours for payroll?
Divide the minutes past the hour by 60 and add them to the whole hours. For 7 hours 48 minutes, 48 ÷ 60 = 0.8, so the entry is 7.8 hours, not 7.48.
How many hours is 90 minutes?
90 minutes is 1.5 hours, which is 1 hour 30 minutes. 120 minutes is exactly 2 hours.
Why is 30 minutes 0.5 hours and not 0.3?
Because an hour has 60 minutes, and 30 is half of 60. Decimal hours are fractions of an hour, so 0.3 h would be only 18 minutes.
How do I convert minutes to hours in Excel?
If a cell holds a number of minutes, use =A1/60. If it holds a time such as 7:48, use =A1*24, because spreadsheets store times as fractions of a 24-hour day.
How many hours is 100 minutes?
100 minutes is 1.6667 hours, which is 1 h 40 min.
What is 15 minutes in hours?
15 minutes is 0.25 hours, a quarter of an hour.
How many hours is 200 minutes?
200 minutes is 3.3333 hours, or 3 h 20 min.
What is 40 minutes in hours?
40 minutes is 0.6667 hours, two thirds of an hour. On a two-decimal timesheet it becomes 0.67.
How many hours is 480 minutes?
480 minutes is exactly 8 hours, a standard full-time workday.
What is 50 minutes in hours?
50 minutes is 0.8333 hours, or 0.83 on a two-decimal timesheet.
