Pound (abbreviations: lb, or lbs, or ps): is a unit of force used in some systems of measurement including English Engineering units and the British Gravitational System. Also, it is a unit of mass used in the imperial, United States customary and other systems of measurement.
Atomic Mass Unit (abbreviations: amu, or u): also known as dalton (symbol: Da), is a standard unit of mass that used on an atomic or molecular scale (atomic mass). One unified atomic mass unit is about the mass of one nucleon (either a single proton or neutron) and equivalent to 1 g/mol.
How to Convert Pounds to Atomic Mass Units
Example: How many atomic mass units are equivalent to 72.23 pounds?
As;
1 pounds = 2.732E+26 atomic mass units
72.23 pounds = Y atomic mass units
Assuming Y is the answer, and by criss-cross principle;
Y equals 72.23 times 2.732E+26 over 1
(i.e.) Y = 72.23 * 2.732E+26 / 1 = 1.9733236E+28 atomic mass units
Answer is: 1.9733236E+28 atomic mass units are equivalent to 72.23 pounds.
