This converter handles elapsed durations, not clocks or time zones. Every included unit has a fixed length.
Durations are normalized through seconds. Months and years are excluded because calendar durations vary.
Example formula: hours × 3,600 = seconds
The conversion engine uses standardized constants and keeps calculation precision separate from display formatting. Your entered values stay in this browser and are not added to the URL or sent to the server.
Their lengths vary by calendar position and leap year, so they are not exact fixed-duration units.
No. Use the dedicated Time Zone Converter to compare local times in cities.
