Good to know

  • Free for any site, commercial or not.
  • The calculator resizes itself to fit your page and follows your readers’ light or dark mode.
  • Calculations run in the reader’s browser — nothing is stored.
  • The small credit line is appreciated but optional. Please don’t embed it on pages that target under-18s.
