What is the lens focal length conversion coefficient of a 16mm film camera relative to Full 35mm?

The exposure area of ??16mm film is 22X16mm, which is about 1.5 times that of the full-frame 36X24mm of 135 film, so the coefficient is 1.5.

For example: 135 full-frame lens 50mm, the area covered on 16mm film is 50X1.5=75mm lens coverage.
