Convert Time Units (ps, ns, µs, ms, s …)

Convert a quantity of time from one unit to another — picoseconds, nanoseconds, microseconds, milliseconds, seconds, minutes, hours, days, or weeks.

{ } How to use

  1. Enter the amount to convert.
  2. Pick the unit to convert from and the unit to convert to.
  3. The result updates as you change the units.

{ } How it works

Convert Time Units (ps, ns, µs, ms, s …) works on the text you provide. Adjust the options, then select Process ▸ and it runs entirely in your browser — nothing is uploaded to a server — then shows the result in the Output panel.

Inputs

  • Amount — paste or type your input in the left panel (use Sample for an example)
  • From — choose one — Picoseconds (ps), Nanoseconds (ns), Microseconds (µs), Milliseconds (ms), Seconds (s), Minutes (min), Hours (h), Days, Weeks (default: Seconds (s))
  • To — choose one — Picoseconds (ps), Nanoseconds (ns), Microseconds (µs), Milliseconds (ms), Seconds (s), Minutes (min), Hours (h), Days, Weeks (default: Milliseconds (ms))

Output

TXT text — copy or download it from the Output panel.

{ } Common uses

  • Convert a duration in milliseconds from a log into minutes.
  • Express a timeout in the unit a configuration file expects.
  • Turn nanoseconds from a benchmark into something you can read.

{ } Limitations

  • Months and years are not offered, and that is deliberate: neither has a fixed length, so any factor would be a convention rather than a conversion. The units run from picoseconds to weeks.
  • The conversion is one multiply and divide in double-precision floating point, so extreme ratios carry the usual rounding. Results are trimmed to twelve significant digits to hide the noise.
  • A week is exactly seven days and a day exactly 86,400 seconds. Leap seconds are not modelled.

{ } FAQ

Is my data uploaded to a server?

No. Everything runs locally in your browser — your files never leave your device.

Can I process more than one file at once?

This tool works on one input at a time.

Is this tool free?

Yes — it’s completely free and needs no sign-up.

Why can I not convert to months?

Because a month is not a fixed quantity of time. February is 28 days or 29, and the rest are 30 or 31, so “one month in seconds” has no single answer. Use Time Between Dates when you need the real span between two actual dates.
