In 1974, 7-Up became the first American soft drink to use the metric measurement system. The move presented a massive marketing opportunity due to the then-national interest in adopting the metric system.

The rebranding coincided with Congress passing the Metric Conversion Act of 1975, which sparked official metric-conversion efforts. 7-Up participated in these efforts by producing Metric Education Kits for distribution in U.S. schools. This interest in metric system adoption declined during the early 1980s, but 7-Up and other sodas continue to use metric instead of imperial measures.
