Formula
seconds = value x unit factor (1 min = 60 s, 1 h = 3,600 s, 1 d = 86,400 s, 1 yr = 365.25 d, 1 month = 1/12 yr)Understanding Time Conversion
The second is the SI base unit of time. Minutes, hours, days and weeks are fixed multiples of it. Months and years are not fixed in the calendar, so this converter uses averages: a year of 365.25 days (the Julian year used in astronomy) and a month of one twelfth of that, about 30.44 days. For exact calendar spans between two dates, use a date difference calculator instead.
Tips and Best Practices
- 1There are 86,400 seconds in a day and 604,800 in a week.
- 2A year is about 8,766 hours using the 365.25 day average.
- 3For payroll or deadlines use real dates; averages are for estimates.
Real-World Example
A 3.5 hour flight lasts 3.5 x 60 = 210 minutes, which is 12,600 seconds. A 52 week year is 364 days, one day short of the 365 day calendar year.
Common Mistakes to Avoid
- Assuming every month has 30 days; the average is 30.4375 days.
- Using 365 days for a leap-year-sensitive calculation.
- Mixing minutes and decimal hours, for example reading 1.5 hours as 1 hour 5 minutes (it is 1 hour 30 minutes).
