FAQ
How many seconds are in a minute, an hour, and a day?
There are 60 seconds in a minute, 3,600 seconds in an hour, and 86,400 seconds in a day — this converter uses these exact ratios in every calculation.
Can this converter handle decimal or fractional values?
Yes. Enter any decimal count and the converter calculates the exact result instead of rounding it to a whole unit first.
Does this converter use a calendar month and year, or average lengths?
It uses average lengths: a year is 365.2425 days — the mean Gregorian year the 4/100/400 leap rule produces — and a month is exactly one twelfth of it, 30.436875 days. So here 1 year ≈ 365.24 days and 1 month ≈ 30.44 days. A named year is exact instead: 365 days, or 366 in a leap year.
