How to Convert Metric Ton to Milligram
- 1 t = 1000000000 mg
- 1 mg = 1 × 10⁻⁹ t
- Example: convert 15 t to mg: 15 t = 15 × 1000000000 mg = 15000000000 mg
Formula
mg = t × 1000000000
Derivation from SI units:
- 1 t = 1000 kg (accepted for use with the SI)
- 1 mg = 10⁻⁶ kg = 10⁻³ g
- 1 t = 1000 kg ÷ 0.000001 kg per mg = 1000000000 mg
Both units are defined exactly, so the factor is exact. Metric Ton definition: metric ton; Milligram definition: milligram.
Worked examples
- A reading of 3 t converts to 3000000000 mg.
3 t × 1000000000 = 3000000000 mg - A value of 25 t is 25000000000 mg.
25 t × 1000000000 = 25000000000 mg
