Converter Calculator

1 35mm equivalent focal length (mm) =
0.266667 Focal length (mm)

Explanation

Smartphone 1/1.3" class uses crop factor 3.75 and sensor width 9.6 mm. focal_mm = equivalent_mm / 3.75. For input 1 eq mm, output is 0.266666666667 mm.

For 35mm equivalent focal length to Focal length, the active sensor profile determines the conversion constants applied to every value.
