1. You can see the atomic mass unit will be, excuse me. Let me go at it a different way.

2. Such as kilogram of mass unit , Kelvin of thermodynamic temperature , Joule of energy unit , Ampere of electric current intensity and Newton of force unit and so on?

3. That just means our mass unit becomes the area unit.

4. Thereby proposes a method to classify fabric thickness by means of the mass unit fabric area or the linear density sum of warp and weft.

5. As a result, 1/12 the mass of a carbon 12 atom is called one ATOMIC MASS UNIT, which is approximately the mass of one PROTON or one NEUTRON. Also called relative atomic mass.
