Worth knowing
metric tonne: Three different tons are in circulation and they differ by up to 12 percent. The metric tonne is 1000 kg, the US short ton is 2000 lb (907.18474 kg), and the UK long ton is 2240 lb (1016.0469088 kg).

How the conversion works
Multiply by 1.000000000e-09 to go from milligram to metric tonne, or divide by it to go back. Every conversion on this site routes through the SI value (kg) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? metric tonne to milligram: 1 t = 1,000,000,000 mg.
