Convert Time Instantly

Yes, absolutely! Our time converter is 100% free with no hidden costs, no premium tiers, and no limitations. You can perform as many conversions as you want without paying anything.

We use official standard conversion factors with high precision. Our conversions are accurate to many decimal places, suitable for scientific and professional applications.

We support 40 time units across 5 categories: SI units (seconds, milliseconds, nanoseconds), common (minutes, hours, days, weeks), scientific (Planck time, shake), astronomical (sidereal year, tropical year), and historical (fortnight, score, jubilee).

Yes! Every conversion page shows the exact factor used. Time conversions use simple multiplication by conversion factors based on the relationship to seconds.

Astronomical time units like sidereal year, tropical year, and Julian year are precise measurements used in astronomy. They account for Earth's orbital variations and are more accurate than calendar years.

We support scientific units including nanoseconds, picoseconds, femtoseconds, Planck time (the smallest meaningful unit of time), and shake (used in nuclear physics).

Historical units include fortnight (14 days), score (20 years), olympiad (4 years), lustrum (5 years), and jubilee (50 years) - terms used throughout history for various periods.

Yes! Our converter is built as a Progressive Web App (PWA). You can install it on your device and use it completely offline.

We automatically adjust precision based on the conversion values. You'll see practical precision levels suitable for both everyday use and scientific applications.

Absolutely! Our converter is fully responsive and works great on smartphones, tablets, and desktop computers. The interface adapts to your screen size.
