Convert Seconds (35mm, 24fps) to Feet of film: Film & Video
Formula
feet = seconds × 1.5 (35mm 4-perf at 24 fps = 90 ft/min)
Why this matters in film & video
35mm four-perf runs 16 frames per foot, so at 24 fps it consumes 1.5 feet per second, or 90 feet per minute, the classic figure for loading mags and budgeting stock.
