Frequently Asked Questions
How many seconds are in one hour?
1 hour = 60 minutes = 3,600 seconds. 1 day = 86,400 seconds, 1 week = 604,800 seconds.
What are milliseconds, microseconds, and nanoseconds?
1 second = 1,000 milliseconds (ms), 1 millisecond = 1,000 microseconds (μs), 1 microsecond = 1,000 nanoseconds (ns). Nanoseconds are commonly used for computer clock cycles — a 1 GHz CPU cycle = 1 nanosecond.
How many seconds are in a month?
Using the average month length of 30.44 days, 1 month ≈ 2,629,746 seconds. Different months have different numbers of days (28–31), so this tool uses the Gregorian calendar yearly average.
