To convert atomic mass units to milligrams, multiply the value by 1.66054 × 10⁻²¹. To go the other way, multiply milligrams by 6.02214 × 10²⁰ to get atomic mass units.
| Atomic Mass Units (u (Da)) | Milligrams (mg) |
|---|---|
| 1 u (Da) | 1.66054 × 10⁻²¹ mg |
| 5 u (Da) | 8.3027 × 10⁻²¹ mg |
| 10 u (Da) | 1.66054 × 10⁻²⁰ mg |
| 25 u (Da) | 4.15135 × 10⁻²⁰ mg |
| 50 u (Da) | 8.3027 × 10⁻²⁰ mg |
| 100 u (Da) | 1.66054 × 10⁻¹⁹ mg |
| 250 u (Da) | 4.15135 × 10⁻¹⁹ mg |
| 500 u (Da) | 8.3027 × 10⁻¹⁹ mg |
| 1,000 u (Da) | 1.66054 × 10⁻¹⁸ mg |
| 2,500 u (Da) | 4.15135 × 10⁻¹⁸ mg |
| 5,000 u (Da) | 8.3027 × 10⁻¹⁸ mg |
| 10,000 u (Da) | 1.66054 × 10⁻¹⁷ mg |
| 100,000 u (Da) | 1.66054 × 10⁻¹⁶ mg |
| 1,000,000 u (Da) | 1.66054 × 10⁻¹⁵ mg |
25 u (Da) × 1.66054 × 10⁻²¹ = 4.15135 × 10⁻²⁰ mg
Try this example →250 u (Da) × 1.66054 × 10⁻²¹ = 4.15135 × 10⁻¹⁹ mg
Try this example →Atomic mass unit (u (Da)). The atomic mass unit (dalton) is 1/12 of the mass of a carbon-12 atom.
Milligram (mg). A milligram is one thousandth of a gram, used for medicine doses and nutrition labels.
There are 1.66054 × 10⁻²¹ milligrams in one atomic mass unit.
Multiply the number of atomic mass units by 1.66054 × 10⁻²¹. For example, 10 atomic mass units equal 1.66054 × 10⁻²⁰ milligrams.
One milligram equals 6.02214 × 10²⁰ atomic mass units.
1.66054 × 10⁻¹⁸ milligrams. Other common values: 100 atomic mass units = 1.66054 × 10⁻¹⁹ milligrams and 10,000 atomic mass units = 1.66054 × 10⁻¹⁷ milligrams.
