Tabele de echivalenta -- Equivalence tables
AWG <--> mm. ISO <--> WhitWorth. mm <--> in.
Tabelele echivaleaza aproximativ valorile standardizate cele mai apropiate, nu sunt rezultatul unor calcule exacte!

 These tables give the approximate equivalence of the closest standardized values, they are not the result of exact computations!

ATENTIE!
Tabelul se refera la tevile de CONSTRUCTIE,  pentru care dimensiunea caracteristica este diametrul exterior. Tevile de instalatii au ca dimensiune caracteristica diametrul interior. De exemplu, o teava de instalatii din cupru de 3/8 va avea diametrul interior de cca. 10mm si cel exterior mai mare cu dublul grosimii de perete
BEWARE!
The table below reffers to the CONSTRUCTION pipes, for which the characteristic dimension is the external diameter. The pipes for fluids instead, have the internal dia as main dimension. I.e., a copper water pipe of 3/8 will have the external dia. bigger with  its double thickness.
