To convert atomic mass units to tonnes, multiply the value by 1.66054 × 10⁻³⁰. To go the other way, multiply tonnes by 6.02214 × 10²⁹ to get atomic mass units.
| Atomic Mass Units (u (Da)) | Tonnes (Metric Tons) (t) |
|---|---|
| 1 u (Da) | 1.66054 × 10⁻³⁰ t |
| 5 u (Da) | 8.3027 × 10⁻³⁰ t |
| 10 u (Da) | 1.66054 × 10⁻²⁹ t |
| 25 u (Da) | 4.15135 × 10⁻²⁹ t |
| 50 u (Da) | 8.3027 × 10⁻²⁹ t |
| 100 u (Da) | 1.66054 × 10⁻²⁸ t |
| 250 u (Da) | 4.15135 × 10⁻²⁸ t |
| 500 u (Da) | 8.3027 × 10⁻²⁸ t |
| 1,000 u (Da) | 1.66054 × 10⁻²⁷ t |
| 2,500 u (Da) | 4.15135 × 10⁻²⁷ t |
| 5,000 u (Da) | 8.3027 × 10⁻²⁷ t |
| 10,000 u (Da) | 1.66054 × 10⁻²⁶ t |
| 100,000 u (Da) | 1.66054 × 10⁻²⁵ t |
| 1,000,000 u (Da) | 1.66054 × 10⁻²⁴ t |
25 u (Da) × 1.66054 × 10⁻³⁰ = 4.15135 × 10⁻²⁹ t
Try this example →250 u (Da) × 1.66054 × 10⁻³⁰ = 4.15135 × 10⁻²⁸ t
Try this example →Atomic mass unit (u (Da)). The atomic mass unit (dalton) is 1/12 of the mass of a carbon-12 atom.
Tonne (t). A tonne (metric ton) is 1,000 kilograms, used for vehicles, cargo, steel and crops.
There are 1.66054 × 10⁻³⁰ tonnes in one atomic mass unit.
Multiply the number of atomic mass units by 1.66054 × 10⁻³⁰. For example, 10 atomic mass units equal 1.66054 × 10⁻²⁹ tonnes.
One tonne equals 6.02214 × 10²⁹ atomic mass units.
1.66054 × 10⁻²⁷ tonnes. Other common values: 100 atomic mass units = 1.66054 × 10⁻²⁸ tonnes and 10,000 atomic mass units = 1.66054 × 10⁻²⁶ tonnes.
