Seconds Converter
Enter a finite non-negative number of seconds to see equivalent standardized time units.
A QUICK WALKTHROUGH
How to use this tool
- Enter a finite, non-negative number of seconds.
- Choose Convert to calculate every supported time unit.
- Review or copy the equivalent values.
Supported fixed units
The converter reports nanoseconds, microseconds, milliseconds, seconds, minutes, hours, days, weeks, months, and years. A day is exactly 24 hours and a week is exactly 7 days.
Standardized month and year conventions
A month is fixed at 30 days and a year is fixed at 365 days. These are duration conventions, not calendar months or calendar years; leap years, dates, and time zones are not inferred.
Safe local conversion
Enter a finite, non-negative value that remains within JavaScript safe numeric conversion. Negative, non-finite, malformed, or unsafe values are rejected. Calculation runs locally in your browser.
GOOD TO KNOW
Common questions
Is a month a calendar month?
No. This converter uses a fixed 30-day month.
Is a year a calendar year?
No. It uses a fixed 365-day year, so leap years and dates are not part of the calculation.
Can I enter a negative value?
No. Seconds must be finite and non-negative.
