To convert atomic mass units to kilograms, multiply the value by 1.66054 × 10⁻²⁷. To go the other way, multiply kilograms by 6.02214 × 10²⁶ to get atomic mass units.
| Atomic Mass Units (u (Da)) | Kilograms (kg) |
|---|---|
| 1 u (Da) | 1.66054 × 10⁻²⁷ kg |
| 5 u (Da) | 8.3027 × 10⁻²⁷ kg |
| 10 u (Da) | 1.66054 × 10⁻²⁶ kg |
| 25 u (Da) | 4.15135 × 10⁻²⁶ kg |
| 50 u (Da) | 8.3027 × 10⁻²⁶ kg |
| 100 u (Da) | 1.66054 × 10⁻²⁵ kg |
| 250 u (Da) | 4.15135 × 10⁻²⁵ kg |
| 500 u (Da) | 8.3027 × 10⁻²⁵ kg |
| 1,000 u (Da) | 1.66054 × 10⁻²⁴ kg |
| 2,500 u (Da) | 4.15135 × 10⁻²⁴ kg |
| 5,000 u (Da) | 8.3027 × 10⁻²⁴ kg |
| 10,000 u (Da) | 1.66054 × 10⁻²³ kg |
| 100,000 u (Da) | 1.66054 × 10⁻²² kg |
| 1,000,000 u (Da) | 1.66054 × 10⁻²¹ kg |
25 u (Da) × 1.66054 × 10⁻²⁷ = 4.15135 × 10⁻²⁶ kg
Try this example →250 u (Da) × 1.66054 × 10⁻²⁷ = 4.15135 × 10⁻²⁵ kg
Try this example →Atomic mass unit (u (Da)). The atomic mass unit (dalton) is 1/12 of the mass of a carbon-12 atom.
Kilogram (kg). The kilogram is the SI base unit of mass, used for body weight, groceries and luggage worldwide.
There are 1.66054 × 10⁻²⁷ kilograms in one atomic mass unit.
Multiply the number of atomic mass units by 1.66054 × 10⁻²⁷. For example, 10 atomic mass units equal 1.66054 × 10⁻²⁶ kilograms.
One kilogram equals 6.02214 × 10²⁶ atomic mass units.
1.66054 × 10⁻²⁴ kilograms. Other common values: 100 atomic mass units = 1.66054 × 10⁻²⁵ kilograms and 10,000 atomic mass units = 1.66054 × 10⁻²³ kilograms.
