Metric American football

...the colleges of Carleton and St. Olaf held the first NCAA-sanctioned metric football game. The “Liter Bowl,” played on September 17, 1977, featured a gridiron measuring 100 meters (109.36 yards) long and 50 meters (54.68 yards) wide. The expanded dimensions favored St. Olaf’s outside running game. The Oles ended up winning the contest—which was supposed to be a game of centimeters—by a score of 43-0.
