Try this example →250 µg × 6.02214 × 10¹⁷ = 1.50554 × 10²⁰ u (Da)
Try this example →Microgram (µg). A microgram is one millionth of a gram, used for vitamins, medicines and trace amounts.
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 × 10¹⁷ atomic mass units in one microgram.
Multiply the number of micrograms by 6.02214 × 10¹⁷. For example, 10 micrograms equal 6.02214 × 10¹⁸ atomic mass units.
One atomic mass unit equals 1.66054 × 10⁻¹⁸ micrograms.
7.22657 × 10¹⁸ atomic mass units. Other common values: 5 micrograms = 3.01107 × 10¹⁸ atomic mass units and 100 micrograms = 6.02214 × 10¹⁹ atomic mass units.
