To convert milligrams to tonnes, multiply the value by 1 × 10⁻⁹. To go the other way, multiply tonnes by 1,000,000,000 to get milligrams.
| Milligrams (mg) | Tonnes (Metric Tons) (t) |
|---|---|
| 1 mg | 1 × 10⁻⁹ t |
| 5 mg | 5 × 10⁻⁹ t |
| 10 mg | 1 × 10⁻⁸ t |
| 25 mg | 2.5 × 10⁻⁸ t |
| 50 mg | 5 × 10⁻⁸ t |
| 100 mg | 1 × 10⁻⁷ t |
| 250 mg | 2.5 × 10⁻⁷ t |
| 500 mg | 5 × 10⁻⁷ t |
| 1,000 mg | 1 × 10⁻⁶ t |
| 2,500 mg | 2.5 × 10⁻⁶ t |
| 5,000 mg | 5 × 10⁻⁶ t |
| 10,000 mg | 1 × 10⁻⁵ t |
| 100,000 mg | 0.0001 t |
| 1,000,000 mg | 0.001 t |
Milligram (mg). A milligram is one thousandth of a gram, used for medicine doses and nutrition labels.
Tonne (t). A tonne (metric ton) is 1,000 kilograms, used for vehicles, cargo, steel and crops.
There are 1 × 10⁻⁹ tonnes in one milligram.
Multiply the number of milligrams by 1 × 10⁻⁹. For example, 10 milligrams equal 1 × 10⁻⁸ tonnes.
One tonne equals 1,000,000,000 milligrams.
1 × 10⁻⁶ tonnes. Other common values: 100 milligrams = 1 × 10⁻⁷ tonnes and 10,000 milligrams = 1 × 10⁻⁵ tonnes.
