<p>Is there a good site/app for calculating this?</p>

### Answer by username_1 on 2012-01-31. Score: 6 | Accepted answer

4,051 feet of film.

For reference:

* 8mm = 80.0 frames per foot
* Super 8 = 72.0 frames per foot
* 16mm = 40.0 frames per foot
* 35mm 2-perf = 32.0 frames per foot
* 35mm 3-perf = 21.3 frames per foot
* 35mm = 16.0 frames per foot
* 65mm = 12.8 frames per foot

The math:

> 60 minutes = 3600 seconds, 3600 sec x 24 fps = 86,400 frames, 86,400/21.333 = 4,050.06328
