That is the accepted size of a given pipe. If you use precise enough measurements, it will vary very slightly. If you say a pipe is 1 1/2 inches, everyone knows what you mean and it is close enough for practically any operation.

What is external diameter?
The diameter is the measurement of a line that goes right through a circle, through the centre point. In cases where we have a ring or some other such object with multiple circles, we would have an external diameter and an internal diameter. The internal diameter is the diameter of the inner circle. The external diameter is the diameter of the outer circle.
What are the Dimensions of a CD?
A standard CD:- 15mm Internal diameter, 120mm external diameter, 1.1 mm thick A mini CD:- 15mm Internal diameter, 80mm external diameter, 1.1 mm thick
How do you find the thickness of a wall using internal and external diameter?
If it is a diameter then you must be in a cylinder or domed room. To get the thickness take the external and subtract the internal then divide the result in half.
How do you calculate internal diameter of chimney if thickness is 25cm?
Subtract 50cm from external diameter.
How do you measure diameter?
Internal diameter.

What is nominal bore of a pipe?
The nominal bore of a pipe is its internal diameter. The nominal bore determines how much volume you have in the pipe to transport your particular substance.
What are the Dimensions of a CD?
A standard CD:- 15mm Internal diameter, 120mm external diameter, 1.1 mm thick A mini CD:- 15mm Internal diameter, 80mm external diameter, 1.1 mm thick

How do you find the thickness of cylinder?
External diameter minus internal diameter will get you the difference and then you have to divide by two to get the wall thickness. (as the difference in diameter accounts for both sides of the cylinder)
How do you measure the dimension of chain sprocket?
External diameter, internal diameter, and tooth count.
How do you calculate internal diameter of chimney if thickness is 25cm?
Subtract 50cm from external diameter.
What is Nominal diameter and Outside Diameter?
nominal diameter is the original diameter of an object
What is difference between nominal diameter of a pipe and bore of pipe and also defined the nominal diameter of pipe and tube how you differentiate both?
bore of the pipe is the internal diameter of pipe but the nominal diameter of pipe is the dia of a circle which is draw through a point which is situates at exactly half of the thickness of pipe or we can say that (outer dia of pipe- thickness of pipe )=nominal bore of pipe.
What is 50NB pipe?
NB = Nominal Bore. Bore is the internal diameter of the pipe. The 50 is referring to 50mm (5cm). So it boils down to a pipe with an internal diameter of 50mm.
What instrument measures the external and internal diameter of a test tube?
A vernier caliper
What is the thickness of centrifugal cast iron pipes 150mm dia?
It is not possible to answer this without more information. However to find the thickness measure the external diameter, measure the internal diameter subtract the internal from the external and that will give you the thickness of the pipe
