    Since the outside diameter is fixed for a given pipe size, the inside diameter will vary depending on the wall thickness of the pipe. For example, 2" Schedule 80 pipe has thicker walls and therefore a smaller inside diameter than 2" Schedule 40 pipe. Steel pipe has been produced for about 150 years.

    Intermediate metal conduit (IMC) is a steel tubing heavier than EMT but lighter than RMC. It may be threaded. Electrical metallic tubing (EMT), sometimes called thin-wall, is commonly used instead of galvanized rigid conduit (GRC), as it is less costly and lighter than GRC. EMT itself is not threaded, but can be used with threaded fittings that ...

    A standard method for sizing tires combines millimeters for overall width and inches for the wheel diameter on which they fit. [117] In lighting, light bulbs use eighths of an inch for bulb diameter and full inches for fluorescent tube lengths, while the socket is always in millimeters (for example, the standard "medium Edison screw" is E26).

    The filler pipe of unleaded fuel is smaller than the one for fuels for engines designed to take leaded fuel. The tank filler opening has a corresponding diameter; this prevents inadvertently using leaded fuel in an engine not designed for it, which can damage a catalytic converter. In most stations in Canada and the US, the pump has a single ...
