You are asking about two sizes of film, but there is no 120mm film that is very popular, the size of 120 is really 60mmx60mm, giving a negative of 2.25 inches x 2.25 inches square. 120 will also give you 645, or 60mm x45 mm, or even 67, which is 60mm x 70mm

They are the dimensions of two types of film commonly used for photography. 35MM is commonly used in Single Lense Reflex Cameras. 120 MM film is used for professional photography because the larger size will yield bigger negatives and allow for greater magnification without grain intruding upon the image. This film is commonly used for models, where graininess will degrade the image.

The width of the film. In digital photography, you are talking about the equivalent based on the size of the sensor array. 7-21mm is equivalent to a 24-84mm lens on 35mm equipment.

when talking about the lens of a camera, focal length of a lense is measured in millimeters as well.
but 35mm & 120mm is the size of the film or in the digital age, the size of the sensor.

That's the physical size of the film itself.
