Try this example →250 t × 6.02214 × 10²⁹ = 1.50554 × 10³² u (Da)
Try this example →Tonne (t). A tonne (metric ton) is 1,000 kilograms, used for vehicles, cargo, steel and crops.
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 × 10²⁹ atomic mass units in one tonne.
Multiply the number of tonnes by 6.02214 × 10²⁹. For example, 10 tonnes equal 6.02214 × 10³⁰ atomic mass units.
One atomic mass unit equals 1.66054 × 10⁻³⁰ tonnes.
7.22657 × 10³⁰ atomic mass units. Other common values: 5 tonnes = 3.01107 × 10³⁰ atomic mass units and 100 tonnes = 6.02214 × 10³¹ atomic mass units.
