"Inch dia" or "inch meter" are units of measurement commonly used for pipe sizes in plumbing and construction. These measurements specify the diameter of the pipe in inches. Inch meters are used when dealing with lengths of pipe measured in meters but still specifying the diameter in inches.
To convert a 6-inch can light to a 4-inch one, you will need to remove the existing 6-inch can and housing and replace it with a new 4-inch can and housing that is compatible with your ceiling. It's important to ensure that the new 4-inch can light is suitable for the space and that any electrical connections are properly handled during the installation.
An inch is larger than a centimeter. One inch is equivalent to 2.54 centimeters.
.187 of an inch is equivalent to approximately 3/16 of an inch.
Electrical wire sheathing should not project more than about one inch into the electric panel.
No, it shouldn't. Electrical work revolves around recommended and non recommended procedures. In this case, the sheathing needs to project no more than about one inch into the electrical panel.
The electric panel is something into which electrical wire sheathing shouldn't project more than about an inch. There are recommended guidelines, and non recommended actions, in electrical work. This is such a case, of recommended actions regarding sheathings and panels.
Electrical wire sheathing should not project by more than one inch into where the wire terminates into a specific device. An example is a junction box or branch circuits terminating into a distribution panel.

B. Electrical panel
Electric wire sheathing should not project more than one inch into the electric panel.
Electric Panel ---------------------------- Based on the answers you have proposed, Electric Panel is the correct choice. However, I do not know of any requirement in the NEC that prohibits the sheathing from extending further into the panel. There is a requirement that it must extend through the connector, but I know of no NEC requirement on when it must stop. --Sparkfighter

When I wire a panel, the outer insulation of the romex does not extend past the romex connector, after the actual conductors have been neatly shaped to the ground / neutral bar and the line has been brought to the breaker the insulation of the hot & neutral is then stripped exposing 1/4 inch of copper then landed.
For a typical 2x4 project, you should use 3-inch screws.
