I'm shooting 3-perf 35mm @ 24 fps. How many feet of film do I need if I'm shooting one hour?
Is there a good site/app for calculating this?
Note: This is a repost of an off-topic/closed question I asked on Photography - Stack Exchange.

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
Tools for Calculating
Kodak makes a free app for iOS called "KODAK Cinema Tools" which has a film calculator, among other features.

Panavision has a simple website with a film footage, frame and running time calculator:

Thank you Fried Of George, I work at a helpdesk for a living, and 'hope this helps' is a habit that I will have to learn to break. :>– filzillaCommented Jan 31, 2012 at 23:35
