Frequently Asked Questions
What time units does this converter support?
Common units include seconds, minutes, hours, days, weeks, months, and years.
How many seconds are in a day?
86,400 seconds (24 hours × 60 minutes × 60 seconds).
How does this handle months, since they have different lengths?
Month-to-other-unit conversions typically use an average month length (around 30.44 days) since calendar months vary between 28 and 31 days.
Is this useful for project planning or scheduling?
Yes — converting between hours, days, and weeks is common when estimating timelines or comparing durations given in different units.
How many hours are in a year?
Approximately 8,760 hours in a standard 365-day year.
Is this tool free to use?
Yes, completely free with no signup, no limits and no software to install.
Is my data saved anywhere?
No — conversions run in your browser and the values you enter are not stored or sent to a server.
Does this account for leap years?
Standard year-length conversions typically use 365 days — for leap-year-specific calculations (366 days), you may need to adjust manually.
Is this useful for converting video or audio duration?
Yes — converting between seconds, minutes, and hours is a common need when working with media file lengths or timestamps.
Can I convert milliseconds?
Yes, sub-second units like milliseconds are typically supported alongside standard time units.
