Duration
Choose conversion type
Convert between time intervals (durations), not clock times. This tool converts seconds, minutes, hours, days, weeks, months, and years for planning, science, and everyday questions. A duration is the length of an event: how long a meeting lasts, how many seconds in a marathon split, or how many days until a deadline. Months and years are not fixed in the calendar sense here—we use an average Gregorian month (about 30.44 days) and a Julian year (365.25 days) so conversions stay single-valued and consistent. For calendar month boundaries (e.g. “next month” on the 15th), use a calendar. Physics and engineering use seconds (SI); everyday life mixes hours and days; project plans use weeks. All calculations run locally in your browser.
Supported units: second (s), minute (min), hour (h), day (d), week (wk), month (mo), year (yr). Month and year use average lengths (see FAQ).

Brief explanation: second to minute
Base conversions: 60 s = 1 min, 3600 s = 1 h, 86400 s = 1 d, 604800 s = 1 wk. Month (mo) uses 2,629,746 s (~30.4369 days). Year (yr) uses 31,557,600 s (365.25 days).
