I did a "Sportsball Fields" conversion tool for calculator. Only thing is it assumes area, not length. It lets me convert between regulation fields for National Football League, International Football Association Board, Canadian Football League, Rugby Union (max and min permissible), Rugby League (max & min) plus curling, and ice hockey (NFL and IIHF). Just need to figure out Australian Rules Football. And then sorry do it all over for length. Anything but metric.
