Are these outside DIA. (copper tube) conversions correct?Hi can anyone confirm if these outside diameters are correct for copper pipe?3/8” 12.7mm?” 15.8mm?”22.22mm Many Thanks!

no copper pipe is measured on the inside not on the out side
Depends on the type of copper tube, if those measurements are what you mic'd then you probably have ASTM B88 type K.
