On one roll of Super 8 film, 15m (50ft) = 2.5 minutes, at 24 frames per second.

I walked 15 meters over 2.5 minutes of an entire roll of Super 8 film outside the Bureau International des Poids et Mesures (BIPM), where the international system of units, including standardized time and length, was developed and defined. The forced synchronicity premised on the structural materiality of film interrogates the notion of measurement, standardization, adaptation, and embodied experience.
