But vaha pr likha hai "as choosen as a standard"

[magic tree]

Iska Matlab kya hua?

[opal bluff]

unit of atomic mass is amu, which is given wrt the Carbon 12 isotope. This is what it means by standard, as it is used as convention throughout the world.

Phir assertion ka real reason Kya hoga ? @opal bluff @hot iris

Tbh i dont understand the last paragraph as well... any insights on the same please?

[hot iris]

That's not the reason it was picked up.
1/12th of C-12 atom represents the mass of 1 proton/neutron (they have about the same mass). And each atom's mass can be expressed as the sum of nucleons * amu.(roughly, for example Cl has a mass of 35.5 amu) It's rather a convention. Another reason is - no other nuclide has an identical whole-number mass on this scale except carbon-12. @full plume @magic tree

Okay thanks a ton @opal bluff @hot iris 🙏
