id means inside diameter, od means outside diameter, copper pipe and tubing is measured by the od, therefore the od the pipe or tubing will be the same as the id of the fitting
The primary difference between pipe and tubing is how the size is designated. Pipe is designated by a "Nominal Pipe Size" based upon the ID (inside diameter) of the most common wall thickness. Tubing is designated by the measured OD (outside diameter). For Example: A 3/4 inch iron pipe has an OD of 1.050 inches, while a 3/4 inch steel tube has an OD of 0.75 inches. The Copper industry calls all cooper tubular products "Tubes" but they designate a "Type". Each type has specified OD and ID dimensions The size of a tube is determined by it's OD and the thickness. The actual OD of a tube is just the same as it's nominal OD. A certain size of a tube will keep the same OD no mater what the thickness is. It is true for pipe except that the actual OD is larger than it's nominal OD. For example, for a 1" schedule 5s pipe, the actual OD is 1.315", the thickness is 0.065" and the ID is 1.185". When it's thickness is schedule xxs (0.358"), then it's ID is reduced to 0.599" while keeping it's OD. Furthermore, the actual OD of a pipe is just the same as it's nominal OD when the size is the same as or larger than 14" per ASME/ANSI B36.10/19 . Consequently, both the size of tube and pipe is measured by it's OD and the thickness. Actually tube is used when we need to transfer heat from its walls and we want this to be happen while in pipes we try to stop the heat transfer such as we use tubes in boilers because we make steam we need to transfer the heat while when we transport steam we use pipes because we wana save heat energy. 2: pipe can be thick according to formula d/t >10 while tube will must thin according to this formula. The Real Difference: Sorry to say; wrong! Pipe and tube is ever so simple. Pipes are used to transport something, and tubes to construct something; hence, tubes are defined by the od "outside diamater" and wt "wall thickness" (for construction stability), and pipes id inside diamater to allow a calculation for transportation viz., speed, volumes etc. (od = id + 2 * wt).
NB = inside diameter of the tube. OD = outside diameter of the tube.

In the USA, 15mm is half-inch, and 22mm is three-quarters inch. Lengths of pipe nipples in these sizes range from one and a quarter/one and a half, to six inches, in half-inch increments.
water line? half inch or three quarters
Yes OD never change
The inside diameter (ID) is 8 inches. The nominal pipe size (NPS) and outside diameter (OD) depend on the thickness of the walls of the pipe.
The answer depends on the thickess of the pipe. The universal formula for carbon steel pipe weight is 10.6802 x T x (OD-T) T=Thickness of pipe OD=Outside Diameter If your pipe was carbon steel with a thickness of .375" it would be 238.8 lbs/ft
Not sure what you mean by pressure fittings. Threaded fittings for steel pipe are pressure fittings. Steel pipe with a 3/4" O.D. is known as 1/2" I.P.S. (Iron Pipe Size) pipe.

Three 0.50 inch diameter pipes will fit into one 1.50 inch diameter pipe (hypothetically). The 0.50 inch diameters stack on top of each other until you have 1.50 inches!
you would need 3 feet of pipe
1/8 pipe schedule
OD is Outside Diameter - at least when you are talking about pipe...
