Table of Equivalent Focal Lengths for APS-C sensor
1

There still seems to be some confusion about focal lengths and effective fields of view (FOV) for cameras with various sensor sizes. Here's a table for the APS-C sensor in my Canon 30D (15mm x 22.5mm).

To make one for your sensor, just find the diagonal using the Pythagorean method. Then calculate focal length FOV as a factor of your diagonal. Then find the 35mm full-frame focal lengths that most closely match those factors.
