Time Converter: A Practical Guide
Use Time Converter to convert fixed durations between seconds, minutes, hours, days and weeks. It treats a day as 24 hours and a week as seven such days. It does not calculate calendar months, years or time-zone transitions.
How to Use Time Converter
- Enter Value in the source unit.
- Choose From and To carefully.
- Select Convert.
- Read the result with its unit and round only as appropriate for the task.
Fixed Duration Units
One minute is 60 seconds, one hour is 3600 seconds, one day is 86400 seconds and one week is 604800 seconds in this arithmetic model.
A civil day during a daylight-saving change can have a different elapsed duration. Calendar months also vary in length. Use date-aware tools when the question concerns actual dates rather than a fixed duration.
Worked Example
150 minutes equals 2.5 hours, which is 2 hours 30 minutes. The decimal .5 is half an hour, not 50 minutes.
Two weeks correspond to 14 fixed days or 336 hours in this model.
Compare two clock times: use the Time Duration Calculator.
Count date-only intervals: use the Date Difference Calculator.
Checks and Common Mistakes
- Do not treat decimal hours as hours-and-minutes notation.
- Do not use a fixed day conversion for timezone-sensitive elapsed time.
- Keep months and years out of this fixed-unit form.
- Check the source unit before converting.
