How the Time Converter works
Enter a duration and choose the units — from milliseconds to years. The result updates as you type, and the table below shows the same duration in every unit.
Seconds, minutes, hours, days and weeks are fixed lengths. Months and years are not, so the converter uses the average Gregorian year of 365.2425 days and an average month of one twelfth of that (30.436875 days). To count real calendar days between two dates, use the Date Difference Calculator.

Formula
result = value × ffrom ÷ fto
Where:
- ffrom
- Size of the starting unit in the base unit (1 h = 3,600 s, 1 d = 86,400 s)
- fto
- Size of the target unit in the same base unit
Average lengths: 1 month = 2,629,746 s and 1 year = 31,556,952 s (365.2425 days).
Examples
10,000 seconds in hours
10,000 ÷ 3,600 = 2.78 h (2 h 46 min 40 s)
One million seconds in days
1,000,000 ÷ 86,400 = 11.57 days
Frequently asked questions
How do I turn decimal hours into hours and minutes?
Keep the whole hours and multiply the decimal part by 60: 7.75 h is 7 h + 0.75 × 60 = 7 h 45 min. Timesheets often use decimal hours.
Why does a month show as 30.44 days?
Calendar months have 28 to 31 days, so a fixed conversion has to use the average: 365.2425 ÷ 12 = 30.436875 days.
Can I add up several durations?
Use the Time Calculator to add or subtract hours, minutes and seconds.
