How it works

The input is normalised to the SI base unit (W) using fixed NIST SP 811 conversion factors, then converted to the target unit. Same-unit conversions return the input exactly.

Assumptions & limits

  • Conversion factors are the exact values published in NIST SP 811.
  • Only the displayed value is rounded; the calculation keeps full precision.

FAQ

Why convert through a base unit?
Normalising every unit to W first means one small, checkable factor table covers every from/to pair without compounding rounding.
