how to convert 60fps videos

The exact question would be how to revert a 24fps video tht was converted to 60fps back to 24fps so it goes back to it's original form!

Depends how it was converted. Upload a sample of a scene with motion of your 60fps video.

In the simple case you can just use a decimation that removes duplicates. For example TDecimate(Cycle=5, CycleR=3) in AviSynth. But as Sharc points out, there are many other cases where it's more difficult.

Keep in mind that modern codecs spend very little bitrate on duplicate frames so reducing 60p (with dups) to 24p will not greatly reduce the bitrate requirement.
