Time Converter is a powerful free online tool available on ToolsMonk that helps you convert between seconds, minutes, hours, and more. Whether you're a professional, student, or casual user, our time converter provides instant, accurate results right in your browser without requiring any software installation or account creation.
As part of our Converters collection, this tool is designed with simplicity and power in mind. All processing happens client-side, ensuring your data remains completely private and secure. The tool works seamlessly across all modern browsers on desktop, tablet, and mobile devices.
Time Converter translates durations between units — seconds, minutes, hours, days, weeks, and more — instantly, saving the mixed-base arithmetic that makes time conversions surprisingly error-prone.
Time doesn't scale by tens like the metric system; it uses 60 seconds to a minute, 60 minutes to an hour, 24 hours to a day, and 7 days to a week. Those irregular factors compound quickly — a day is 86,400 seconds, a week 604,800 — which is precisely where a converter earns its keep, especially in programming for timeouts and cache durations.
One honest limitation: months and years aren't fixed-length (months run 28–31 days, years include leap years), so any conversion involving them is an approximation rather than exact. For the precise gap between two calendar dates, a date calculator is the right tool; the unit converter shines for the consistent seconds-to-weeks range.
Conversion runs in your browser with nothing uploaded. Pair it with the other ToolsMonk converters and the Timezone Converter for the full range of time and unit work.
Memorise the big ones: 3,600 s = 1 hour, 86,400 s = 1 day, 604,800 s = 1 week
For months/years, treat results as approximate — use a date calculator for exact calendar gaps
Great for setting cache TTLs and timeouts without manual multiplication
