Try this example →250 ct × 1.20443 × 10²³ = 3.01107 × 10²⁵ u (Da)
Try this example →Carat (ct). The metric carat is 200 milligrams, the unit for diamonds and gemstones.
Atomic mass unit (u (Da)). The atomic mass unit (dalton) is 1/12 of the mass of a carbon-12 atom.
There are 1.20443 × 10²³ atomic mass units in one carat.
Multiply the number of carats by 1.20443 × 10²³. For example, 10 carats equal 1.20443 × 10²⁴ atomic mass units.
One atomic mass unit equals 8.3027 × 10⁻²⁴ carats.
1.44531 × 10²⁴ atomic mass units. Other common values: 5 carats = 6.02214 × 10²³ atomic mass units and 100 carats = 1.20443 × 10²⁵ atomic mass units.
