Frequently Asked Questions

What time units are supported?

The converter supports seconds, minutes, hours, days, and weeks. Enter a value in any unit and see the equivalent in all others simultaneously, plus an HH:MM:SS formatted display.

How precise are the conversions?

Conversions use standard definitions: 60 seconds per minute, 60 minutes per hour, 24 hours per day, 7 days per week. Results are displayed with up to 4 decimal places for precision.

Can I convert decimal values?

Yes — the converter accepts decimal inputs like 1.5 hours (which equals 90 minutes). All conversions preserve decimal precision throughout the calculation.

How do I convert milliseconds to other units?

Enter the millisecond value divided by 1,000 into the seconds field. For example, 5,000 milliseconds is 5 seconds. The converter then shows the equivalent in minutes, hours, days, and weeks automatically. Milliseconds are commonly used in programming for timeout values and API response times.
