The tool supports, among others:
- nanoseconds and microseconds - for measuring very short distances,
- milliseconds and seconds - typical time measurements in tests and logs,
- minutes and hours - work planning and reporting,
- days, weeks, months and years - long-term schedules.
2. Select the conversion direction

- Single mode– e.g. "minute → hour" or "second → millisecond".
- “All” mode– one input value and a complete conversion table for all units.
Additionally, the unit conversion button allows you to quickly reverse the conversion direction, e.g. fromhours to minutestominutes to hours, without rewriting the values.
3. Set precision, notation and number format
The strength of the time converter is the ability to ha
