How does the duration converter work?
Each field represents an independent duration. All entered values are added together before conversion.
- Enter one or more time values (for example hours or days).
- The converter adds all values into a single total duration.
- The total duration is then displayed as a normalized result and as total values in each time unit.
Examples of duration conversions
- 10,000 hours is converted into years, months, days, hours, minutes and seconds.
- 1 year and 400 days are added together before being converted.
- 90 minutes becomes 1 hour and 30 minutes.
Important notice
Conversions are based on fixed values: 1 year equals 365 days and 1 month equals 30 days. This tool is intended for general time conversions, not calendar-based calculations.
