Diameter.
Pipes are typically measured by their nominal diameter, which refers to the inside diameter (ID) of the pipe rather than the outside diameter (OD). This measurement allows for standardization across various pipe materials and types, facilitating compatibility with fittings and connections. The wall thickness varies depending on the pipe's schedule or classification, but the nominal diameter remains consistent as the primary reference point.

With a paintbrush.
The best way to clean out the inside of your custom motorcycle straight pipes is to remove the pipes and use a cleaning solvent and a rag with a long handled brush.

Fins are attached to the pipes inside the heater to increase the surface area in contact with the surrounding air. This allows for better heat transfer from the hot water inside the pipes to the air outside, improving the overall efficiency of the heater.

Heat exchange pipes in a refrigerator are responsible for transferring heat from the inside of the refrigerator to the outside environment, allowing the refrigerator to maintain a cool temperature inside. The pipes contain a refrigerant that absorbs heat as it evaporates inside the refrigerator and releases it as it condenses outside. This process helps in cooling the interior of the refrigerator.
You are experiencing no water flow in your pipes because the water inside them has frozen, causing a blockage.
The correct dimensions are measured from inside post to post for width, and from the surface to the inside of the crossbar for height
