Tips & notes
  • Linear conversions use a base unit and simple factors (value × factor). Temperature uses offsets (e.g., °C ↔ K) and proper affine formulas.
  • Data can show both SI (KB=1000 B) and IEC (KiB=1024 B). Toggle visibility in the “Data units” box.
  • Significant figures are for display only; calculations keep full precision.
