About the Unix Timestamp Converter
Unix timestamps — the number of seconds since 1 January 1970 — are how computers store time, but they are meaningless to human eyes. Developers constantly need to turn a timestamp like 1700000000 into a readable date, or the other way around, when debugging logs and APIs.
This Unix Timestamp Converter switches between timestamps and human-readable dates instantly, in both directions.
How to use the Unix Timestamp Converter
- Enter a Unix timestamp, or a date and time.
- Choose the direction of conversion.
- The tool converts it.
- Read the human date or the timestamp.
Key features of the Unix Timestamp Converter
- Converts Unix timestamps to dates and back
- Handles seconds-based timestamps
- Instant, accurate conversion
- Essential for developers and logs
- Private — runs in your browser
How the Unix Timestamp Converter works
Every conversion uses the exact, internationally agreed factors defined by the International System of Units (SI) and recognised standards bodies. Temperature conversions apply the correct formulas rather than simple multipliers, and results retain full precision so they are suitable for scientific, engineering and everyday use alike.
All conversions are calculated instantly in your browser.
Tips & best practices
- Watch for seconds versus milliseconds — many systems use milliseconds, which are 1,000 times larger.
- Timestamps are usually in UTC, so account for your time zone when reading the human date.
- Keep the epoch in mind: a timestamp of 0 is 1 January 1970.
Standards & accuracy
Uses precise SI and internationally agreed conversion factors for accurate, standards-based results.
Results are accurate to standard conversion factors. For everyday use you can round sensibly; for scientific, medical or engineering work, keep the full precision the tool provides.

Frequently asked questions
It is the number of seconds that have elapsed since 1 January 1970 (UTC), a standard way computers store time. The converter turns it into a readable date and back.
The standard Unix timestamp is in seconds, but many systems use milliseconds. Check which you have, as they differ by a factor of 1,000.
Timestamps represent UTC. When reading the human date, adjust for your local time zone as needed.
