Try this example →Milligram (mg). A milligram is one thousandth of a gram, used for medicine doses and nutrition labels.
Atomic mass unit (u (Da)). The atomic mass unit (dalton) is 1/12 of the mass of a carbon-12 atom.
There are 6.02214 × 10²⁰ atomic mass units in one milligram.
Multiply the number of milligrams by 6.02214 × 10²⁰. For example, 10 milligrams equal 6.02214 × 10²¹ atomic mass units.
One atomic mass unit equals 1.66054 × 10⁻²¹ milligrams.
7.22657 × 10²¹ atomic mass units. Other common values: 5 milligrams = 3.01107 × 10²¹ atomic mass units and 100 milligrams = 6.02214 × 10²² atomic mass units.
