Utilities

Unit converter

Convert length, mass, temperature, area, volume, time and storage units. Distinguish gallon variants, MB and MiB with local calculations.

Use a decimal point without grouping separators. Up to 1e30; output uses 24 significant digits. MB is decimal and MiB is binary.

Result

0.001 km

What this tool does

Compare everyday measurements without confusing proportional factors with offset temperatures. US liquid and imperial gallons are distinct units; months and years are not approximated as fixed durations.

How to use it

  1. Select a quantity and enter a number with a decimal point.
  2. Choose source and destination; output updates as values change.
  3. Swap units or copy the numeric result for another application.

Verifiable example

Input
0 °C to °F; 1 MB to MiB.
Expected result
32 °F; 0.95367431640625 MiB.

Limitations to review

  • Absolute maximum 1e30; output up to 24 significant digits. Use a decimal point without grouping.
  • Rejects negative mass/length and temperatures below absolute zero. Not a substitute for calibrated or safety-critical engineering calculations.
