  • Definitions are fixed conversion factors. Results are rounded to the selected significant digits.
  • One bounded decimal value and two allowlisted units. Fixed conversion arithmetic; display precision 1-30 significant digits.
  • Use no more than 200,000 characters across the input and settings.
  • Bounded decimal inputs mean at most 120 characters, zero or a magnitude from 10^-100 to 10^100. Arithmetic uses 40-digit precision; exponent suffixes are checked before parsing.
