Method and definitions

  • Linear units convert through the category’s SI base unit.
  • Temperature uses affine Celsius, Fahrenheit, and kelvin formulas.
  • Exact legal/standards definitions are stored as constants; output formatting does not alter the source value.

Limits and edge cases

  • The converter covers the listed everyday units, not every scientific or historical unit.
  • Temperature below absolute zero is rejected.
  • Market defaults are preferences only and never prevent switching units.

Privacy

Values are converted locally without a network request.
