Tons to Milligrams
Convert tons (t) to milligrams (mg). Both measure mass and weight, and the conversion comes up in cooking, shipping, fitness work.
The Formula
``
milligrams = tons × 1000000000
tons = milligrams × 1e-9
`
One ton is 1,000,000,000 milligrams, and one milligram is 1.0000e-9 tons.
Conversion Table
| Tons | Milligrams |
|---|---|
| 1 t | 1,000,000,000 mg |
| 2 t | 2,000,000,000 mg |
| 5 t | 5,000,000,000 mg |
| 10 t | 10,000,000,000 mg |
| 25 t | 25,000,000,000 mg |
| 50 t | 50,000,000,000 mg |
| 100 t | 100,000,000,000 mg |
| 500 t | 500,000,000,000 mg |
| 1,000 t | 1,000,000,000,000 mg |
The Other Direction
| Milligrams | Tons |
|---|---|
| 1 mg | 1.0000e-9 t |
| 2 mg | 2.0000e-9 t |
| 5 mg | 5.0000e-9 t |
| 10 mg | 1.0000e-8 t |
| 25 mg | 2.5000e-8 t |
| 50 mg | 5.0000e-8 t |
| 100 mg | 1.0000e-7 t |
| 500 mg | 5.0000e-7 t |
| 1,000 mg | 1.0000e-6 t |
What Each Unit Is
Tons (t) — here the metric tonne: exactly 1,000 kilograms. From the tun, a large wine cask, whose weight became a trade standard.
Milligrams (mg) — one thousandth of a gram. The metric unit for doses and trace quantities.
A Sense of Scale
A small car is about 1.5 t- A cubic metre of water is 1 t
- Shipping freight is priced per tonne
- A grain of sand is about 1 mg
- An aspirin tablet is 300–500 mg
- Nutrition labels use mg for sodium
Precision
The factor 1000000000 is rounded. For engineering work carry more digits than the table above, and round only at the end — rounding at each step compounds.
Watch Out For
- Three different tons exist: metric (1,000 kg), US short (907 kg) and UK long (1,016 kg). This converter uses the metric tonne.
In Code

const tonToMilligram = (value) => value * 1000000000;

How Many Decimals Do You Need?
Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 t with the factor truncated at each decimal place:
| Decimals kept | Factor | 137 t becomes | Error |
|---|---|---|---|
| 0 | 1000000000 | 137,000,000,000 | — |
| 1 | 1000000000 | 137,000,000,000 | — |
| 2 | 1000000000 | 137,000,000,000 | — |
| 3 | 1000000000 | 137,000,000,000 | — |
| 4 | 1000000000 | 137,000,000,000 | — |
The right number of significant figures is set by your input, not by the converter. If you measured tons to three significant figures, the answer in milligrams is only good to three — writing more digits claims precision the measurement never had.
