How to use

  1. 1 Pick a dimension — length, weight, volume, area, time, temperature, speed, data size, or angle.
  2. 2 Enter the value you want to convert.
  3. 3 Choose the unit your value is in. Every other unit in the dimension updates live in the table below.
  4. 4 Click Copy on any row to push that converted value to your clipboard.

Why use this tool

  • Nine dimensions in one tool — no need to bookmark separate length / weight / temperature converters.
  • Live grid shows every unit at once; the row matching your selected From unit is highlighted.
  • Temperature uses linear formulas (offset + scale), so Kelvin / Rankine round-trip correctly.
  • Data sizes distinguish SI (kB, MB, GB) from binary IEC (KiB, MiB, GiB) — both shown side by side.

Frequently asked questions

Why does the tool give 1 month = 30.44 days?

For non-calendar conversions, month is the Gregorian average of 365.2425 / 12 days. If you need exact calendar-month durations between specific dates, use the Date Calculator instead.

What is the difference between kB and KiB?

kB is SI (1000 bytes). KiB is IEC binary (1024 bytes). Storage vendors use SI; operating systems and RAM use binary. The 1024 vs 1000 gap is why a "1 TB" drive shows as ~931 GiB.

Does the tool handle very large or very small numbers?

Yes. Values outside 1e-4..1e15 are displayed in scientific notation to keep precision readable.

Why isn't pressure / energy / fuel economy listed?

They will land in a future phase. For now, this tool covers the nine dimensions that hit 95% of search demand.
